[clang] [Clang] Fix fix-it hint regression from #143460 (PR #144069)

[Ross Kirsling via cfe-commits]

https://github.com/rkirsling created https://github.com/llvm/llvm-project/pull/144069

Following #143460, `:` began displaying as `colon` in the fix-it hint for a `case` with a missing colon, as is visible in the description of (the separate bug) #144052.

This PR simply reverts a line that didn't need to be changed.
