Feature request: search recent failures

[abonander]

While investigating #2244 I didn't really have any choice but to go through Recent Failures page-by-page and check for sqlx-sqlite with Ctrl-F to make sure it just didn't fail to build.

To be fair, if it had gotten picked up and just failed to build, that would have been shown when pulling up the docs for version 0.7.2.

However, a search could still be quite useful, e.g. to check for build failures for all crates in a family simultaneously (like just searching the prefix "sqlx").

I've been doing a lot of thinking about ways to surface build issues to crate owners recently. I'll try and spend some time tomorrow to write up my thoughts.

Assuming #797 is solved, so all failed builds would be visible,

I'm not sure how this would look like.

Perhaps being able to search in the release-lists?

Finally wrote up my ideas in #2434, would a feature like that be more useful for this sort of usecase @abonander?
