What does this change

feat: filter github repositories using topics

What issue does it fix

We have hundreds of repositories and targeting them all or providing a list of repositories is annoying to do so.
It would be nicer just to target repos filtered by topic name.
For example I'd like to add a fix targeting all repos labeled backend.

Thanks for the PR! This is definitely something useful that should be added. However, there are two questions that needs to be answered first.

1. Are topics supported on other platforms? Should be an easy implementation in that case, and I'm happy to test it out if needed.
2. Multiple topics to be filtered are supported in the current implementation, which should be the case. But I'm unsure if it should be that all topics specified must exist, or if any of the topics has to exist. (The latter is implemented). Any input here? :)

I did not check yet as I don' use any other platform atm. But might have a look if I find the time.

I asked myself the same question. I came to the conclusion that it makes more sense to match if any exists. Although this might be a matter of taste. But it should not get complicated for a user to configure it so I went with the later. Might just be a matter of documentation.

Taking a quick look, it seems that topic exist in:

✔️ GitHub
✔️ GitLab
❌ BitBucket server
✔️ Gitea

If you are unfamiliar with GitLab and GitLab, I could add it in this PR.

Taking a quick look, it seems that topic exist in:

heavy_check_mark GitHub heavy_check_mark GitLab x BitBucket server heavy_check_mark Gitea

I will have a look 👍🏻

[raffis]

Added support for gitlab and gita. Although I doubt topics is a widely used feature in gitea since I didn't even see the option in the ui to set topics.
Will add a story test once everything else is confirmed.

Great with the added SCMS! Looks good, but there are some minor changes to be made.

LGTM 👍 Just a test in tests/story_test.go and it should be ready to merge 😄

[lindell]

Thanks for the contribution 😄 Are you ready to have it merged?
