Simplify check-dumpfile to do the same as compinit

first because simpler is usually better, and second because we cannot
always guarantee that the .latest_comp file, which was holding the list
of all completion functions, is consistently in sync with the dumpfile
that is generated afterwards.

 ### Added
 
 - `check-dumpfile` action. It runs in the build, install and update actions, and checks if a
-  new completion configuration needs to be dumped. It's more powerful than `compinit`, which
-  just checks if the number of completion functions and the Zsh version changed. The
-  `check-dumpfile` action also checks if the actual list of completion functions changed. It's
-  intended to be used with `compinit -C`, so no checks are done during the shell startup.
