fix(gha-lint): allow lint workflow to be triggered by github-actions[bot] (#41)

## what

- Use the `on: pull_request_target` event in lint workflow.

## why

- GitHub Actions workflows configured with `on: pull_request` do not
trigger for Pull Requests created by the default github-actions[bot]
user. This leads to PRs being "blocked" or "pending checks"
indefinitely, _if repository rulesets require those checks._
- pull_request_target runs from the base repository's context, allowing
it to be triggered by github-actions[bot].
