Node.js 12 actions are deprecated. For more information see: https://github.blog/changelog/2022-09-22-github-actions-all-actions-will-begin-running-on-node16-instead-of-node12/. Please update the following actions to use Node.js 16: dawidd6/action-get-tag@v1

These warnings are coming from:

zsv/.github/workflows/ci.yml

Lines 37 to 41 in 3ea6750

	uses: dawidd6/action-get-tag@v1
	if: startsWith(github.ref, 'refs/tags/v')
	id: tag
	with:
	strip_v: true

The rest of the actions have already been updated earlier for NodeJS updates.

https://github.com/dawidd6/action-get-tag has been archived by its author.

As an alternative, the tag can directly be extracted and set like this (lines copied here for quick reference):

    - name: Get tag if tagged/released and set TAG env var
      if: startsWith(github.ref, 'refs/tags/v')
      run: |
        TAG=$(echo $GITHUB_REF | cut -d '/' -f3)
        echo "TAG: $TAG"
        if [[ $TAG == "v"* ]]; then
          TAG="${TAG:1}"
        fi
        echo "TAG: $TAG"
        echo "TAG=$TAG" >> $GITHUB_ENV

I'll submit a PR shortly. Thanks!
