Adlsgen2 fixes (#1974)

* Modified create_or_get_group Function. Added the mailEnabled and mailNickname properties.

* Changed  the conditional check in the adlsgen2setup.sh script. The change from -n to -z ensures that the script correctly verifies whether the AZURE_ADLS_GEN2_STORAGE_ACCOUNT environment variable is set and non-empty before proceeding. This is the intended behavior to avoid running the script without the necessary configuration.

* Added a comment to inform the developer to resolve a potential AAD tenant issue in adlsgen2setup.py
