Add support for feeds

[filoozom]

In order to be able to deploy production websites to Swarm, it would be easy useful for this action to support feeds.

This could be done either by conditionally replacing swarm-cli upload with swarm-cli feed upload and adding inputs for:

• topic
• topic-string
• identity

Or adding a separate action that runs swarm-cli feed update.

What would be your preference? I'd be happy to write a PR. 🙂

Yeah, support for Feeds makes definitely sense! PR will be very appreciated!

I think it would make more sense to create another step for the feed update if the inputs for this are specified and use the swarm-cli feed update. It seems you will have to do some hacking as the swarm-cli identity import requires a file to import the identity. Let me know if you need help!

I ended up re-implementing the actions I needed in a new monorepo, because I wasn't quite sure it would fit in nicely here.

The objective was to be quite modular, by having the "smallest" actions possible (although I didn't really to that for write-feed, where the manifest is systematically created): https://github.com/filoozom/swarm-actions/blob/main/.github/workflows/test.yml
