[llvm] [Docs] Fix broken LLVM doc pages (PR #68631)

[Aiden Grossman via llvm-commits]

https://github.com/boomanaiden154 created https://github.com/llvm/llvm-project/pull/68631

These pages have warnings due to the links not being moved during the myst transition and maybe some breakages afterwards. This causes the docs build to fail as warnings are treated as errors by default. This patch fixes these issues for llvm/*.
