deps: support Unicode 16 via utf8proc 2.10.0 (#56925)
Similar to #51799, support [Unicode
16](https://www.unicode.org/versions/Unicode16.0.0/) by bumping utf8proc
to 2.10.0 (thanks to https://github.com/JuliaStrings/utf8proc/pull/277
by @eschnett).
This allows us to use [7 exciting new emoji
characters](https://www.unicode.org/emoji/charts-16.0/emoji-released.html)
as identifiers, including "face with bags under eyes"
`"\U1fae9"` (but still no superscript "q").
Closes #56035.
