mac: review allowed system fonts

I noticed that Apple Color Emoji is not in Catalina, first shows up in 11 Big Sur

NOTE: except 10.15 + 11, lists don't distinguish between built-in vs downloadable

• catalina 10.15: https://support.apple.com/en-us/101429
• big sur 11: https://support.apple.com/en-us/101430
• monterey 12: https://support.apple.com/en-us/103203
• ventura 13: https://support.apple.com/en-nz/103197
• sonoma 14: https://support.apple.com/en-nz/108939
• sequoia 15: https://support.apple.com/en-us/120414

We should check this, unless we're ok with splitting mac users into two groups - maybe catalina will be dropped next ESR?
