xxl alias for 2xl breakpoint in attributify mode

[toniengelhardt]

In principle I prefer the 2xl, 3xl, etc. syntax over xxl, xxxl, ..., e.g. text-4xl and so forth. But there is a problem with breakpoints in attributify mode where 2xl:something doesn't work (probably bc it cannot start with a number?). The workaround is to use class="2xl:something", which works, but is not very elegant.

My suggestion would be to add xxl as alias for 2xl, xxxl as alias for 3xl, etc. only for the default breakpoints if that is possible.

Makes sense
