rustdoc: remove the word "Version" from test cases

Needed for rust-lang/rust#115948 to merge.

That PR gets rid of the word "Version" in rustdoc's HTML output, and it splits spaced versions on their first space, to fit in the tight horizontal spacing. This causes Cargo's test suite to fail, because it look for the word "Version", even though things are working as they should.

These tests work on both current nightly and on that pull request.
