Use proper RST code directives in docstring of QB in method

[GeigerJ2]

See 4b941ab#r2604198271 for details.

The issue this PR fixes started appearing on the v2.7.2 release branch, but went previously unnoticed on main, as API auto-doc got removed in #7056 before.

At least I saw it looking pretty once on the RTD build, even though it will probably never re-appear on main :')

Nice find! I don't really understand RST, but I trust that you verified that this fixed the problem on the release branch?

Be glad, formatting is quite the pain. Yes, the screenshot is from there, it doesn't even appear here on main currently, without api auto-doc. Had to verify there and then port the change over main to make this PR. Cheers!
