Update mongodb.json

--Update the regex validation for MongoDb version so valid numeric version (semver) is only acceptable (3.10 is ok but 3. is not)
--Update the regex for password so it can accept also special character, and make it stricter for password
--Update the password description to state more information about what password should it be
