Pull Request resolved: https://github.com/facebook/react-native/pull/46295
X-link: https://github.com/facebook/metro/pull/1343
Updated all **babel** packages in all `package.json` across the repo and ran `npx yarn-deduplicate yarn.lock --scopes babel`. Afterwards, fixed the following issues appearing as a result of that (squashed the following initially separate diffs to make this packages update work atomically):
### (D61336392) updated jest snapshot tests failing
### (D61336393) updated babel types and corrected typings accordingly
The latest babel 7 introduces the following features we need to adjust our types to:
* `JSXNamespacedName` is removed from valid `CallExpression` args ([PR](https://github.com/babel/babel/pull/16421))
* `JSXNamespacedName` is used for namespaced XML properties in things like `<div namespace:name="value">`, but `fn(namespace:name)` doesn't make any sense.
* Dynamic imports are enabled behind a new flag `createImportExpressions` ([PR](https://github.com/babel/babel/pull/15682)), introducing calls such as `import(foo, options)`. These complicate the expected values passed to `import` to be more than just strings.
* Since these are behind a flag that is not expected to be enabled, we can throw an error for now and whoever uses it can add a support to it if needed later.
### Added a new metro ENV ignore
`BROWSERSLIST_ROOT_PATH` is set to `""` explicitly in `xplat/js/BUCK`
and then ignored in
`js/tools/metro-buck-transform-worker/src/EnvVarAllowList.js`

Summary:
See https://github.com/facebook/react-native/issues/41929 for an issue on multiple monorepo packages being installed. The reason is that `*` resolves to whatever is tagged `latest` on npm.
We still need to fix the fact that our monorepo publish script will update the latest tag everytime we publish. For now, we should remove these from `main` and we will also update this in the 0.73 release branch.
I've left the two peer dependencies on `react-native` to keep at `*`.
```
virtualized-lists/package.json
30: "react-native": "*"
rn-tester/package.json
32: "react-native": "*"
```
As a peer-dependency this won't be a problem in terms of installing a second `react-native`. I thought about updating these to `nightly`, but that would install multiple nightly react-natives as the tag will be updated with each nightly release. I think for now this is fine and something we can revisit.
Things left to do
[ ] Fix monorepo publish script to not update `--latest`
[ ] Remove ^ dependencies on monorepo packages: https://github.com/facebook/react-native/pull/41958
[ ] Re-evaluate how we bump and align monorepo packages when we cut a release branch. I forget if we manually update this when we cut or if there is a script. We may want to change the script and have `main` dependencies point to some fake version like `1000.0.0` and only update these on nightly publishes. Regardless, this will need some discussion.

Bump `hermes-parser` packages to the latest released version.
Changelog: https://github.com/facebook/hermes/blob/main/tools/hermes-parser/js/CHANGELOG.md
Notable changes:
- Upgraded to the lastest version of emscripten for the parser.
- The babel interop logic now more closely matches babel's AST.
- The biggest change is we now add the `extra.raw` properties to literal nodes, which results in Babel more closely outputting literal sources. e.g. previously the following would happen `1.0` -> `1`, `'foo'` -> `"foo"` and `1n` -> `1` but now the raw source value is preserved.
- Upgraded `prettier-plugin-hermes-parser` to use the latest prettier formatting logic, which causes some minor formatting changes.
- `hermes-parser` no longer fails when the `component` name is used within a function type, e.g. `type Foo = (component: string) => void`.

Metro has been passing `inlineRequires: false` to Babel transformers for the last 5 years (D9636747), as the inline requires transform had been hoisted into the transform worker. Here we clean up the unused code paths in React Native's implementations of the Metro Babel transformer API, and the unused properties in the API itself.
