std/core docs: fix wrong link in PartialEq

PartialEq doc was attempting to link to ``[`Eq`]`` but instead we got a link to `` `eq` ``. Disambiguate with `trait@Eq`.

You can see the bad link [here](https://doc.rust-lang.org/std/cmp/trait.PartialEq.html) (Second sentence, "floating point types implement PartialEq but not Eq").
