Hi!
First of all, thank you for this action!

So here is our issue, it seems like the label isn't applied anymore. Here you can find the logs:

This is the dev workflow we have enabled:

name: Size Labeler

on: [pull_request]

jobs:
  labeler:
    runs-on: ubuntu-latest
    name: Label the PR size
    steps:
      - uses: codelytv/pr-size-labeler@v1
        with:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}
          xs_max_size: '10'
          s_max_size: '100'
          m_max_size: '500'
          l_max_size: '1000'
          fail_if_xl: 'false'
          message_if_xl: >
            'This PR exceeds the recommended size of 1000 lines.
            Please make sure you are NOT addressing multiple issues with one PR.
            Note this PR might be rejected due to its size.’
