Clippy links to `master` instead of actual version

Hello everyone,

whenever Clippy suggests a change, it links to further information on its website.
However the link always directs to master, hence if a lint-name changes, the link becomes invalid.

One example is cognitive_complexity.

We can find it on master: https://rust-lang.github.io/rust-clippy/master/index.html#cognitive_complexity
But not on v0.0.212, as there seems to be a name-change: https://rust-lang.github.io/rust-clippy/v0.0.212/index.html#cyclomatic_complexity

It once linked me: https://rust-lang.github.io/rust-clippy/master/index.html#cyclomatic_complexity
To no success obviously.

It would be great if Clippy would link to the correct version. E.g. v0.0.212 links to https://rust-lang.github.io/rust-clippy/v0.0.212
I would be willingly to contribute this change too!

Thanks for your time, keep the great work up : )

The issue names no file or test. Start by locating the code that constructs Clippy's lint-help links, then compare its generated URL with the versioned Clippy documentation for the reported example. Done means a v0.0.212 link points to that version rather than master, including the renamed lint target.
