I'm not sure, but we can't use branch names in this workflow, only tag names?

@datamweb I sent PR https://github.com/codeigniter4/.github/pull/26

[datamweb]

[Invalid workflow file: .github/workflows/smart-commenting.yml#L20](https://github.com/codeigniter4/shield/actions/runs/8398026883/workflow)
The workflow is not valid. .github/workflows/smart-commenting.yml (Line: 20, Col: 3): Error calling workflow 'codeigniter4/.github/.github/workflows/label-signing.yml@main'. The workflow is requesting 'pull-requests: write', but is only allowed 'pull-requests: none'.

~~But why we have set access pull-requests: write in .github https://github.com/codeigniter4/.github/blob/567aab8e987fccac5b1864d0635ec087b12d0866/.github/workflows/label-signing.yml#L12-L14~~
