ci: Remove DMG staging directory to prevent Sentry from walking its /Applications symlink (#7687)

`sentry-cli debug-files upload` offers no option to exclude certain
files or directories when recursively searching the given path. Thus, we
need to remove this staging directory to prevent it from recursively
walking the directory and inevitably erroring out when it hits a path it
doesn't have access to.
