Actions fails unless GITHUB_TOKEN is explicitly provided

[manio143]

I've a good hour trying to debug why the action was failing for my repo. Turns out the GITHUB_TOKEN value was blank.
By default the action uses github.token which is empty. Instead secrets.GITHUB_TOKEN needs to be used.

pr-size-labeler/action.yml

Lines 4 to 7 in 1c34223

	GITHUB_TOKEN:
	description: 'GitHub token needed to interact with the repository'
	required: false
	default: ${{ github.token }}

Also would be good to check for that in the script, because it runs all the way, but jq fails to parse response from GitHub API when it's not in an expected format. It fails but the script isn't aware why and doesn't print anything that could point to an authorization issue.

Work around:

steps:
- uses: codelytv/pr-size-labeler@v1
  with:
    GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

Not working for me, still getting this error:

/src/main.sh: line 14: /root/bin/docpars: cannot execute binary file: Exec format error
/src/main.sh: line 19: github_token: unbound variable

Could anyone help? I've used previously GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }} in other GitHub Actions, but not on this one.
