chore: remove jest, ts-jest, @nx/jest dev dependencies (#942)

* chore: remove jest, ts-jest, @nx/jest, and related dev dependencies

All packages have been migrated to vitest (#935-#940). This drops the
jest runtime entirely:

- Remove root jest.config.ts and jest.preset.js
- Remove @nx/jest:jest target config from nx.json
- Drop devDependencies: @nx/jest, @types/jest, babel-jest,
  eslint-plugin-jest, jest, jest-chrome, jest-environment-jsdom,
  jest-util, ts-jest
- Drop the eslint-plugin-jest plugin and its no-focused-tests rule
  registration from the root eslint config
- Drop **/jest.setup.{js,ts} from the root eslint config's
  no-extraneous-dependencies override scope
- Drop **/jest.config.js from beachball ignorePatterns
- Update lockfile

Note: this PR depends on #935, #936, #937, #938, #939, #940 — merge
those first.

* chore(devtools): use explicit vitest imports

@types/jest was previously providing global describe/it/expect types for
@griffel/devtools' tests. With it removed, switch the tests to explicit
`import { describe, it, expect, vi } from 'vitest'` and drop the now-unused
`vitest/globals` types entry / `globals: true` from vite.config.ts —
matching @griffel/core's style.
