Summary:
Pull Request resolved: https://github.com/facebook/react-native/pull/35767
Changelog: [Internal]
Introducing a script, which can be used to identify all packages inside `/packages`, which contain any changes after the last time its version was changed
How it works step by step:
```
check that no git changes are present
for each package:
if package is private -> skip
grep id of the last commit that changed package
grep id of the last commit that changed version of the package
if these ids are different:
bump package patch version
commit changes if required
```
Can be executed only in git environment and by running: `node ./scripts/bump-all-updated-packages`
---
Also adding a separate script `align-package-versions.js`, which can be used to update versions of packages inside consumer packages
```
check that no git changes are present
for each package x:
for each package y:
if y has x as dependency:
validate that y uses the latest version of x
if some changes were made:
run yarn
```

Q: Why `run_yarn` step was removed from CircleCI flow?
A: For *-stable branches, there are no yarn workspaces and all packages are specified as direct dependencies, so if we update `react-native/assets-registry` to the next version, we won't be able to run `yarn` for react-native root package, because updated version is not yet published to npm
To avoid this, we first need publish new versions and then update them in consumer packages
---
The final flow:
1. Developer uses `node ./scripts/bump-all-updated-packages` to bump versions of all updated packages.
2. Commit created from step 1 being merged or directly pushed to `main` or `*-stable` branches
3. A workflow from CircleCI publishes all updated versions to npm
4. Developer can use `align-package-versions.js` script to create required changes to align all packages versions
