Change permissions for cloned repositories

The current user and group ID are passed passed to the docker build command
and the ownership of the cloned directories are changed to them.
This gets rid of git's "dubious ownership" error.

Without this changes I got an error:
> $ make
> docker run --rm -v :/var/www/en -w /var/www -u 1000:1000 php/doc-en
> configure.php on PHP 8.2.29, libxml 2.9.14
>
> fatal: detected dubious ownership in repository at '/var/www/doc-base'
> To add an exception for this directory, call:
>
> 	git config --global --add safe.directory /var/www/doc-base
> doc-base/temp clean up FAILED.
> make: *** [Makefile:22: xhtml] Fehler 1
