[PATCH v5 0/1] ci: new github-action for git-l10n code review

[Jiang Xin <worldhello.net@gmail.com>]

From: Jiang Xin <zhiyou.jx@alibaba-inc.com>

## Changes since v4

* "git-po-helper check-commits" can work with bare repository now. So do not use
  "actions/checkout@v2" to prepare workspace any more.

* "git-po-helper learned how to fetch missing blobs in a batch. So do a blobless
  partial clone.
