For the `useId` algorithm we used colon `:` before and after.
https://github.com/facebook/react/pull/23360
This avoids collisions in general by using an unusual characters. It
also avoids collisions when concatenated with some other ID.
Unfortunately, `:` is not a valid character in `view-transition-name`.
This PR swaps the format from:
```
:r123:
```
To the unicode:
```
«r123»
```
Which is valid CSS selectors. This also allows them being used for
`querySelector()` which we didn't really find a legit use for but seems
ok-ish.
That way you can get a view-transition-name that you can manually
reference. E.g. to generate styles:
```js
const id = useId();
return <>
<style>{`
::view-transition-group(${id}) { ... }
::view-transition-old(${id}) { ... }
::view-transition-new(${id}) { ... }
`}</style>
<ViewTransition name={id}>...</ViewTransition>
</>;
```
