Export OPML for Category

[yusixian]

Clear and concise description of the problem

I want export opml of all feeds under one of my categories so that I can edit him to batch replace the rsshub address for other instances.

I intend to submit a PR for this issue

Suggested solution

Is it possible to put this function on the right-click menu of the category? Or will there be a better category management revamp in progress?
