Fix spelling of "compatible" and "compatibility"

In racket#5425
commits 8086563
and 3014b7d,
I spelled "compatible" and "compatibility" consistently as
"compatable" and "compatability".

`git grep compatab` and `find . | grep compatab`

Fixing the filename requires a cross-repo change (with this and
racket/compatibility#17), so it'll be the
second cross-repo breaking change in ~3 hours, but it seems better
to do it now than wait until later or leave the misspelling there
forever.
