chore: fileadmin is a shared dir of the TYPO3 13 deployment

fileadmin moves from the TYPO3 10 release
(ep-reisen-typo3/shared/public/fileadmin) to
ep-reisen-typo3-13/shared/public/fileadmin, so Deployer links it like the
other shared dirs (relative symlink) and the typo3:fileadmin task with
its absolute fileadmin_path goes.

deploy:shared creates a missing shared dir empty, which would leave the
sites without any file: deploy:check:fileadmin aborts the deploy before
anything happens on the server if the shared fileadmin is missing. Deploy
this only after the directory has been moved.
