Many GHC docs links are broken

Summary

Location of documentation issue:

URLs such as https://downloads.haskell.org/ghc/latest/docs/html/users_guide/profiling.html do not exist. However, https://downloads.haskell.org/ghc/9.0.2/docs/html/users_guide/profiling.html does exist, for instance.

It seems that this is because https://downloads.haskell.org/ghc/latest/docs/users_guide/ is the correct base URL: the html component was removed from the URL.

This URL change has broken Google results among many many other links to the ghc documentation. I suspect that it may also be contributing to Google's very unfortunate habit of returning ancient GHC versions' documentation (Haskell is not the only language with this problem though; Python 2 links were on top for a very long time).

Proposed improvements or changes

Consider creating a redirect.
