[Feature] String search

[crumblingstatue]

Sometimes I have a huge output, and I would like to be able to quickly find a lint/error/etc. of interest.

Example use case

• I enable clippy::pedantic
• There is tons of warnings, so I toggle summary view to find interesting lints
• I see an interesting lint that I would like to enable, but the summary view doesn't show the lint name
• I untoggle summary view, but that resets the scroll, so I'm not at the same lint anymore
• I need a way to find that lint again in the sea of output (by searching for part of the lint message), but there is no search feature

I reflexively reach for /, since it's a standard binding in a pager for string search, so that would be a nice default binding for it.

You can be confident I couldn't choose any other one ;)
