Bump @babel/core, @babel/eslint-parser, @babel/plugin-transform-runtime,
and @babel/runtime to ^8.x. Remove useESModules and regenerator options
from @babel/plugin-transform-runtime config (both removed in Babel 8).
Switch @babel/eslint-parser import from the removed /experimental-worker
entry point to the main entry point.
Bump vite to ^8.0.0 (now using Rolldown/Oxc instead of esbuild/Rollup).
Bump @rollup/plugin-babel to ^7.1.0 and
babel-plugin-ember-template-compilation to ^4.0.0.
Patch ember-concurrency@5.2.0 to remove the api.assertVersion(7) call
that is incompatible with Babel 8 (ember-concurrency has not yet
released a Babel 8-compatible version).
