Link problems in generated docs

[SEIAROTg]

I noticed in some generated docs there are different symbols with same name. For example in purescript-typelevel-prelude@3.0.0/Type.Row, there are two Cons, one being a class re-exported from Prim.Row while the other being a type from Prim.RowList. Both of them have the anchor #t:Cons which creates ambiguity. I suggest we use a different prefix for type classes, so they will be #c:Cons and #t:Cons.

Also all links to Prim are currently dead in that page as it's assuming Prim in the same package.

These are both compiler issues, so I've created purescript/purescript#3502 and purescript/purescript#3504 to track them. Thanks for the report!
