feat(issue triage): Get all labels of the repository (#346)

Use a loop on the paginated API to collect all the labels of the repo,
as the current implementation only get 30 of them.

I did not modified the current workflows you are using
[here](https://github.com/google-github-actions/run-gemini-cli/blob/main/.github/workflows/gemini-triage.yml),
but if it makes sense for you I can update the PR.

We might think about an additional option to use specific patterns to
select only some labels lately?

Thanks in advance for the review
