Improve error messages for {option,result}_map_unit_fn
Instead of saying "unit function", use the phrase the description uses: "function that returns the unit type".
Fixes#5180.
changelog: Improve error messages for {option,result}_map_unit_fn
Mention the setup instructions in CONTRIBUTING
Multiple people seem to have missed this based on questions asked in the Discord channel. Might as well mention it up front.

Rename macro_use_import -> macro_use_imports
I missed this during review of #5230. We can just do this, without deprecating the old name, since this lint didn't hit nightly rustc yet.

Fix deploy script for tag deploys
By hand updating the documentation for the `rust-1.41.1` release, I found, that the deploy script was buggy for tag deploys. Luckily we weren't affected yet (will only run if the commit of the tag already has the workflow config, so probably ~`rust-1.43.0`)
The bug:
When a tag was deployed, until now it also updated the master documentation to the state of the tag. This was because the `git add .` not only updated the files created or modified by the tag commit, but also the master lints.json file.
