Fix up the label for writing assistance in Markdown fields.
Review Request #15076 — Created May 25, 2026 and submitted — Latest diff uploaded
The new setting for enabling spell checking, dictation, AI assistants,
etc. in Markdown-enabled fields was artificially limited, just referring
to spell checking. This change updates that label and help text to be
more comprehensive, and fixes the documentation to match.
Verified the label in the UI.
