feat: Flag plural nouns after numbers when they work together as qualifiers

[hippietrail]

This is very common among non-native speakers and I've been getting the impression that it's just starting to spread into young native English speakers too.

• A ten years old kid → A ten year old kid
• A 64 bits CPU → A 64 bit CPU

Actually, multi-word qualifiers should be written with hyphens connecting all the words, but this should be a separate setting/preference since it seems to have largely fallen out of favour in the last couple of decades:

• A ten-year-old kid
• A 64-bit CPU

But even so you sometimes even see things like this:

• A ten-years-old kid
• A 64-bits CPU

Here I'll collect ones I see in the wild:

• Yep, it's a 50-minutes episode!
• A 56 minutes long video by Jimmy?
