This is the v3 equivalent of PR #13596

Matching for the hyphen character in the existing regex to use support
queries as-is

Resolves #13594

Tests (w/ updated):
- ✅ `supports-[display:grid]:grid`
- ✅ `supports-[transform-origin:5%_5%]:underline`
- ✅ `supports-[not(foo:bar)]:underline`
- ✅ `supports-[(foo:bar)or(bar:baz)]:underline`
- ✅ `supports-[(foo:bar)and(bar:baz)]:underline`
- ✅ `supports-[(foo:bar)_and_(bar:baz)]:grid`
- ✅ `supports-[(foo:bar)_and_(bar:baz)_or(baz:qux)]:grid`
- ✅ `supports-[container-type]:underline`
- ✅ `supports-grid:underline`
- ✅ `supports-[--test]:flex`
- ✅ `supports-[selector(A_>_B)]:underline`
- ✅ `supports-[font-format(opentype)]:grid`
- ✅ `supports-[font-tech(color-COLRv1)]:flex`
