🔡 Add default document font to the font selection list #489
Description
Currently, the default font used for Lexical documents is active by default but does not appear as a selectable or highlighted option within the font dropdown list.
To improve the user experience and consistency, the default document font should be explicitly included in the font list. This allows users to:
- Easily see which font is currently active.
- Switch back to the default styling after experimenting with other fonts.
