Incorrectly assuming all links with /c/ are Lemmy links

Issue

Clicking on links with paths that start with /c/rest-of-path get incorrectly treated as a Lemmy link.

Example

https://catbox.moe/c/rk6abk

So when clicked within app, Thunder tries to open it as if it were a community.

I believe I need some stronger regex rules for figuring out lemmy links - linking this since it seems like we can follow lemmy-ui's regex:

https://github.com/LemmyNet/lemmy-ui/blob/021677316d290062a8c3bafdbec668dd8ebb3b85/src/shared/config.ts#L31-L39

Unfortunately that regex is pretty limited in what it matches. It requires the full community@instance name.

EDIT: I don't know how we can definitively/preemptively determine that a given link goes to a Lemmy instance. Maybe we can ping it with the API client?

[ajsosa]

Yeah that's probably the simplest solution. Do a ping to check if the community exists and have that decide how to open link.

This fix should be in the latest general release.
