Inkscape 1.3 is missing the sans-serif font alias

Summary:

Old files created by 1.2.x have text with a font specified as 'sans-serif' but 1.3 says that doesn't exist with a warning triangle.

Steps to reproduce:

• Create or find an old document with 1.2.x that has editable text with the font set to 'sans-serif'
• Open said document with Inkscape 1.3
• Edit text, note font has a triangle next to it
• Change font to 'Sans', see triangle goes away

What happened?

The UI says 'sans-serif' is not recognized (warning triangle in the font dropdown).

What should have happened?

It should be a recognized keyword, as support was added for 'sans-serif' in a prior version to match what CSS recognizes, iirc.

Obviously this is low-priority since it defaults to the same font as Sans (at least on Windows), but hopefully it's also easy to add back. 🙂
