refactor(highlight)!: rename attributes to match Vim (#19159)

Ref: https://github.com/vim/vim/commit/84f546363068e4ddfe14a8a2a2322bb8d3a25417
Rename:
- `underlineline` to `underdouble`
- `underdot` to `underdotted`
- `underdash` to `underdashed`

`underdouble` also now takes higher precedence than `undercurl`.
