Unless I've overlooked something (possible!), the guide to Git branching at https://github.com/newtfire/textAnalysis-Hub/blob/main/gitBranching-Guide.md explains how to delete a local branch that is no longer needed, but not how to delete the corresponding remote branch on GitHub. Deleting a branch locally doesn't remove it automatically from GitHub; if you want it to disappear from your GitHub repo, you need to delete it there separately from deleting it locally. A stale remote branch may be clutter, just like a stale local branch, so removing it helps make your GitHub repo easier to understand.
In most cases, the command to delete a remote branch (that is, to make it disappear from your GitHub repo) will be:
git push -d origin name-of-branch-to-delete
