Broken source links from base-4.19.0.0 haddocks to ghc-prim
https://hackage.haskell.org/package/base-4.19.0.0/docs/GHC-Exts.html#v:listThreads-35- has a "Source" link to https://hackage.haskell.org/package/ghc-prim-0.11.0-997e/docs/src/GHC.Prim.html#listThreads%23 which doesn't exist, because it contains part of the ABI hash. The correct link should be https://hackage.haskell.org/package/ghc-prim-0.11.0/docs/src/GHC.Prim.html#listThreads%23.
