Subject: [PATCH] doc/_ext: Remove unnecessary f-string formatting

Replace f-string with plain string when no variable interpolation is needed.

The f-string "<empty-string>" contains no placeholders or variables, making
the f-prefix unnecessary. Using a plain string is more appropriate and
slightly more efficient.
