Rollup merge of #53060 - iliekturtles:rustdoc-style, r=GuillaumeGomez

Change rustdoc style so fully qualified name does not overlap src link

A type's fully qualified name will now wrap once it gets to the
`[-][src]` link aligned against the right edge of the content area.
Previously the two would overlap and the name would only wrap when
hitting the edge of the content area.
