[code-infra] Make useReactVersion script reusable in other repos

[cherniavskii]

For MUI X, I duplicated the useReactVersion.mjs script in mui/mui-x#13360, but eventually, I want to use the script from the monorepo.
I've extracted the CLI to a separate file, so now other repos ca import the setReactVersion function.

Not going to block this PR, but if it's just to pass a workspace root path I'd consider just sharing the cli like we do with the changelog script. Less code to maintain and less implicit API shared between repos.

[cherniavskii]

@Janpot Hmm, do you mean something like this? node ./useReactVersion.mjs /workspace/root/path?
I don't have a strong preference, I can do that 👍🏻

[Janpot]

Yes, it's just a suggestion, I have a preference but it's not a strong one neither 😄

[cherniavskii]

@Janpot I looked into this, and it seems that I have to use the getWorkspaceRoot function anyway to always get the correct workspace path regardless of the directory from which the script was called. Alternatively, I can use process.cwd(), but that would lead to different results depending on the CWD (e.g. node ./scripts/useReactVersion.mjs and cd scripts && node useReactVersion.mjs would behave differently).
Given the above, I would prefer keeping the current approach with function export.
Does this make sense to you? Or am I missing something?

When the script is run as a package.json script then process.cwd() will always be the folder that contains the package.json, even when run from a subfolder. My hope is for our internal tooling to mimic tools like eslint and prettier and distribute them as a CLI. In fact, In time I'd like to add a bin script to our repo so that dependent projects can just do something like "use-react-version": "mui-infra use-react-version" without any other setup required.

Right, I didn't think about this!
Added a use-react-version script and used process.cwd() instead of getWorkspaceRoot() 👍🏻

perfect

As a next step, we could move it to @mui/internal-scripts so it can be referenced from the npm package in other repos.
