chore(deps): bump all @babel/* packages to v8

[dependabot]

Bumps all @babel/* packages used across the repo to their latest 8.x versions (extending the original @babel/template 7.29.7 → 8.0.0 bump).

Changes Made

• Dependency bumps (all source package.json files):
  • @babel/core → ^8.0.1
  • @babel/generator, @babel/helper-module-imports, @babel/traverse, @babel/template → ^8.0.0
  • @babel/helper-plugin-utils, @babel/preset-react, @babel/preset-typescript → ^8.0.1
• Deduplication: ran yarn dedupe.
• Babel 8 code migration (required by Babel 8 breaking type changes):
  • PluginObj → PluginObject, TransformOptions → InputOptions, BabelFileResult → FileResult
  • Swapped the declare<State, Options> generic order in @babel/helper-plugin-utils usages (babel-preset, postcss-syntax, webpack-extraction-plugin)
  • api.assertVersion(7) → api.assertVersion('^7.0.0 || ^8.0.0') to support both majors
  • Source-map type casts at the webpack this.callback boundary (Babel 8's EncodedSourceMap vs webpack's RawSourceMap)
  • Explicit PresetObject return type on griffelPreset to fix a type-portability error
• Change files: added patch beachball entries for @griffel/babel-preset, @griffel/postcss-syntax, @griffel/webpack-loader, and @griffel/webpack-extraction-plugin.

Testing

• ✅ Type-check passes (20 projects)
• ✅ Build passes (15 projects)
• ✅ Lint passes
• ✅ Tests pass (17 projects, including the rspack legacy + modern e2e scenarios)

@copilot bump all used @babel/* packages across the repo to latest versions i.e. 8.x.x, do yarn dedupe, add change files with type patch

Done in b7535f1. Bumped all @babel/* packages to 8.x (core 8.0.1, generator/helper-module-imports/traverse/template 8.0.0, helper-plugin-utils/preset-react/preset-typescript 8.0.1), ran yarn dedupe, and added patch change files for @griffel/babel-preset, @griffel/postcss-syntax, @griffel/webpack-loader, and @griffel/webpack-extraction-plugin.

Babel 8 has breaking type changes, so I also migrated the affected code: PluginObj→PluginObject, TransformOptions→InputOptions, BabelFileResult→FileResult, the swapped declare<State, Options> generic order, assertVersion('^7.0.0 || ^8.0.0'), and source-map type casts at the webpack callback boundary. Type-check, build, lint, and tests (incl. rspack e2e) all pass.

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version. You can also ignore all major, minor, or patch releases for a dependency by adding an ignore condition with the desired update_types to your config file.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
