Prior to 6.3.0, we were able to `import { extractMessages, getSettings }
from 'eslint-plugin-formatjs/util.js'`, and we did this to define some
custom rules that are specific to our workflows.

After #6080, that import is
failing.

Can we restore the ability to import the util module?

…port (formatjs#6437)

## Summary
- Add `./ts-jest-integration.js` to the `exports` field in
`package.json`
- Add `ts-jest-integration.ts` as a rolldown entry point in
`BUILD.bazel` so it gets bundled with `.js`, `.d.ts`, and `.js.map` into
the published package
- Update jest integration test config to use `.js` extension in the
import path

This was a regression from formatjs#6080 which added an `exports` field to
`package.json` but only included `.` — blocking the
`ts-jest-integration` deep import that ts-jest users rely on.

Closes formatjs#6433

## Test plan
- [x] `bazel test //packages/ts-transformer:package_exports_test` —
validates all exports resolve to real files
- [x] `bazel test //packages/ts-transformer:unit_test` — 27 tests pass
- [x] All pre-commit hooks pass
