Ruslan Lesiutin ec28c5bbaa feat(react-native-github): a script to automate patch version bumping of packages (#35767)
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
