dependabot hasn't picked up on/updated `coveralls` since October 2024

I may be mistaken & it may have been pinned for a reason but there have been 4 updates since last update to v2.23.2 https://github.com/coverallsapp/github-action/releases

actions/download-artifact is also left at v4.1.8 https://github.com/actions/download-artifact/releases

actions/setup-python is also left at v5.3.0 https://github.com/actions/setup-python/releases

we generally pin actions to a specific release to avoid unexpected breakages. I don't see anything immediately earth shaking in the coveralls release notes that would mandate an update, but if you would like to submit a PR to do so, we'd be happy to review it. Thank you!
