Previously, we checked if the target of a projection type was itself an
inference variable. However, for Rustdoc rendering purposes, there's no
distinction between an inference variable ('_') and a type containing
one (e.g. (MyStruct<u8, _>)) - we don't want to render either of them.

Fixes rust-lang#60269

Due to the complexity of the original bug, which spans three different
crates (hyper, tower-hyper, and tower), I have been unable to create a
minimized reproduction for the issue.

Don't try to render auto-trait bounds with any inference variables

Revert "Update Source Code Pro fonts to version 2.030"

Temporary fix for rust-lang#60365

rust-lang#60146 updated all fonts (not just the fonts that were buggy), however it looks like the new Source Code Pro is buggy.

We should test this out of tree: `cargo doc` on anything, replace the font in `target/doc`, and use `python -m SimpleHTTPServer` to see what's going on.

Till we figure that out, I'll just back this out.
