fix: only-issue-types does not affect PRs

[trueberryless]

Description:
When the only-issue-types is set, this should only affect issues, not Pull Requests.
However, since the GitHub API treats PRs and issues all as issues, this type checking was missing and all PRs were ignored if the only-issue-types was set.

Related issue:

• Closes PR check uses only-issue-types #1331

Check list:

• Mark if documentation changes are required.
• Mark if tests were added or updated to cover the changes.

• Skip onlyIssueTypes filtering for pull requests in IssuesProcessor.
• Add a unit test ensuring PRs are not filtered out by onlyIssueTypes.
• Document in README that onlyIssueTypes does not affect PRs.

Thanks for the fix! Looks like check-dist is failing — could you update the generated dist files when you get a chance?

Hi @trueberryless , just a gentle reminder on this one — check-dist is still failing because the generated dist files need to be updated. When you have a moment, could you regenerate and push those changes? Thanks!

Hi! Sorry, I completely forgot to update this last week when you mentioned it first. Should be good to go know 😉
