[compiler] Fix missing dependency in eslint-plugin-react-hooks

[eps1lon]

Summary

#34176 introduced @babel/plugin-proposal-private-methods:

react/packages/eslint-plugin-react-hooks/src/shared/RunReactCompiler.ts

Line 13 in 63feb94

import PluginProposalPrivateMethods from '@babel/plugin-proposal-private-methods';

However, the declared dependencies of eslint-plugin-react-hooks weren't updated.

This mostly worked for package managers that hoist everything but breaks when node_modules are strictly isolated to the set of declared dependencies.

I declared the used dependency in this PR. Could also be possible to use the transform directly.

Fixes

Oops! Something went wrong! :(

ESLint: 9.12.0

Error: Failed to load plugin 'react-hooks' declared in '--config » ./.eslintrc.json': Cannot find module '@babel/plugin-proposal-private-methods'
Require stack:
- ~/node_modules/.pnpm/eslint-plugin-react-hooks@0.0.0-experimental-6de32a5a-20250822_eslint@9.12.0/node_modules/eslint-plugin-react-hooks/cjs/eslint-plugin-react-hooks.development.js

Test plan

• Applied patch via packageExtensions to make the error go away (vercel/next.js@5b2b3a5)

thank you!

[poteto]

this package seems deprecated. rather than update the package here, could you try updating react/packages/eslint-plugin-react-hooks/src/shared/RunReactCompiler.ts to use @babel/plugin-transform-private-methods instead?

[eps1lon]

Good point. I didn't know. Though this was attempted before and reverted in #31665 so I don't think that's safe?

[poteto]

Ah right good catch
