fix: use PR_GH_TOKEN in lint/i18n workflows to trigger e2e tests (#8484)

## Summary

Add `PR_GH_TOKEN` to ci-lint-format and i18n-update-core workflows to
ensure commits trigger e2e test runs.

## Changes

- Add `token: ${{ secrets.PR_GH_TOKEN }}` to checkout step in
`.github/workflows/ci-lint-format.yaml`
- Add `token: ${{ secrets.PR_GH_TOKEN }}` to checkout step in
`.github/workflows/i18n-update-core.yaml`

## Context

This matches the pattern used consistently across all other workflows in
the repository (release-version-bump, version-bump-desktop-ui,
api-update-registry-api-types, i18n-update-nodes, etc.).

Without this token, commits made by these workflows don't trigger
downstream e2e tests, which can lead to issues being missed.

## Original Work

Original idea & implementation by @drjkl in commits:
- be3a8d61c - fix: use GitHub App token for lint/i18n workflows to
trigger e2e tests
- 50ccb254b - Add github app token action to pinact

This PR simplifies the approach to use the existing `PR_GH_TOKEN` secret
instead of GitHub App tokens, for consistency with the rest of the
repository.

## Test Plan

- [x] Verify workflows can checkout code successfully
- [x] Confirm commits from these workflows trigger e2e test runs

## It works!
