fix(admin): Use normalizedPath instead of realpath to check rootRepositories
fix(admin): Use normalizedPath instead of realpath to check rootRepositories

The PHP method `realpath` returns canonicalized absolute pathname. realpath() expands
all symbolic links and resolves references to /./, /../ and extra / characters in the
input path and returns the canonicalized absolute pathname.

The `\Jelix\FileUtilities\Path::normalizePath` resolves references to /./, /../ and
extra / characters in the input path.

In Lizmap, the rootRepositories config parameter could be a symbolic link, in which find
Lizmap repositorires. So Lizmap does not need to expand symbolic link in the admin maps
controller, it only needs to normalize path.
