doc: Use proper tags in pg_overexplain documentation.

The pg_overexplain documentation previously used the <literal> tag for
some file names, struct names, and commands. Update the markup to
use the more appropriate tags: <filename>, <structname>, and <command>.

Backpatch to v18, where pg_overexplain was introduced.
