create-group: document that account is created if LDAP auth succeeds

The 'create-group' command allows to add initial group members with the
'--member' option. Trying to add a user that doesn't have an account in
Gerrit fails, unless LDAP is used for authentication. If LDAP is used
for authentication and the user is not found, Gerrit tries to
authenticate the user against the LDAP backend. If the authentication
is successful a user account is automatically created, so that the user
can be added to the group. Describe this feature in the documentation
of the 'create-group' command.
