Check for broken links in the documentation

[GenevieveBuckley]

I've noticed some broken links in the napari-plugin-engine documentation pages. We should fix these, possibly with the same link checking we do for hte napari.github.io respository: https://github.com/napari/napari.github.io/blob/main/.github/workflows/link-checker.yml

One example of a broken link: on this page the linked named "See also: documentation for writing a napari plugin" produces this 404 error.

Recently Tried to fix that specific link in #42 ... need to figure out why it didn't work.

Did you find any others?

[GenevieveBuckley]

I didn't look for any others, figured it might be quicker to let an automated link checker do that 😄

[tlambert03]

I ask because that might literally be the only page with links in these docs. (Not a lot of links).

But feel free to make a PR with the link checker if you want!

[GenevieveBuckley]

Ah, well then maybe that's overkill. Not super familiar with how extensive these docs are, or how many links.

I'm slightly concerned that if we fix that individual link, and then the reorg shuffles files around, it might just break again (probably what happened here in the first place). So it might make sense to wait a little bit, or schedule a follow up/

[tlambert03]

the reorg no longer uses this repo at all! so no worries there

It is super weird, I don't know why #42 didn't fix things.

I am looking at latest, and it's not a caching issue (I see the same thing happen in a private window).

Was the main branch renamed from master recently? Which branch does github think it's building the docs with?
