Fully document that `@TempDir` can be used on constructor parameters

[sbrannen]

Overview

As a followup to #4060, we need to update the Javadoc and the Annotations section of the User Guide to mention that @TempDir can be used not only on fields and lifecycle/test method parameters but also on test class constructor parameters.

According to the changes in #4060 it's already documented. Did I miss a spot?

The Javadoc has not been updated yet, and although 99% of the User Guide has been updated, the Annotations overview section has not yet been updated.

I originally noticed it in the Javadoc, and quick search in the User Guide led me to believe that it hadn't been done in the User Guide either. So I created this issue to make sure we didn't forget about those spots (because I couldn't reopen the PR).

I just updated this issue's title and description to reflect that.
