rustdoc: remove bad CSS font-weight on `.impl`, `.method`, etc

This line was added in c494a06, because at the time, the headers had these classes on them. Now, the headers are children of the `<section>` with the class on it.

This commit also adds a test case, to make sure the srclink font weight does not regress again.
