Link to ErrorProne has trailing parenthesis

Example job failure in GitHub (https://github.com/mockito/mockito/actions/runs/15985352598/job/45088589864?pr=3674):

```

THIS IS LIKELY A BUG! If you are trying to test the correctness of an equals() implementation, use EqualsTester instead.

When I click on this link in the GitHub output, it leads to `https://errorprone.info/bugpattern/SelfAssertion)`. Which as you can see has the trailing parenthesis included.

Can we add a space before the closing parenthesis such that the URL is properly clickable?
