Fix ESLint v10 RuleContext API removal (follow-up to #3972)

[ledsun]

This PR follows up on the feedback in the comments of #3972 and incorporates the requested changes.

I think this PR will fix #3977.

[ljharb]

we'll need regression tests - it might be as simple as adding eslint 10 to the GHA matrix.

@ledsun do you have time to address the failing checks. I'm looking at updating to eslint 10 and we're using the eslint-plugin-react

[lorand-horvath]

Would it be an option to move to an eslint 10 compatible plugin like eslint-plugin-import-x?

No.

@ljharb Why not? It's not like this one is compatible with eslint 10 or something. When will it be fixed?

[captaindonald]

Yes, it needs to be rebased and the test failures fixed. Please do NOT open a redundant PR; if you have changes you want added, comment with a branch or commit link, and I'll pull them in.

@ljharb I pulled the ESLint 10 RuleTester schema fix out into #4006 — strips ~400 type: references from test files (ESLint 10 dropped type from the error schema) and pins a transitive that's been crashing npm install on node 4/5. Once it merges, rebasing here should leave only a small number of red cells, all of which look like the matrix flakiness tracked in #4007.

Since that PR was merged and so was a PR that closed #4007, can this be rebased? Will that allow this to be merged, or is it also waiting on import-js/eslint-plugin-import#3230 (which needs a new review following rasmi addressing its feedback)?

I rebased and ran some local tests on a fork. I think we are just waiting to get unblocked on [import-js/eslint-plugin-import#3230]. Any remaining cleanup after that should be pretty straight forward.
