Description of problem:

When input a invalid team name in Create team wizard in quay new UI, there is a red help message "Choose a name to inform your teammates about this team. Must match ^[a-z][a-z0-9]+$". But in quay 3.13, some special invalid team names can pass the validation, or the validation process doesn't make sense. 

But the validation for these invalid names works well in quay 3.12.4.

1 If the first character is incorrect, there is no red help message in quay 3.13.

   But there is red help message in quay 3.12.4.

2  In quay 3.13, when input some invalid character, the red help message will show up, but if input valid character continuously, the red help message will gone. 

But it works well in quay 3.12.4

3 Some invalid team names can pass the validation in quay 3.13, such as "a12-b" and "0aa".

All below invalid team names can get correct red help message in quay 3.12.4

['a', 'A', '0', '$', '0aa', 'A12', 'a12-b','a_b', 'a@12', 'abc#', 'abA', 'a%b']; 

But below invalid team names hit some validation problem  in quay 3.13

['a',  '0',  '0aa',  'a12-b','a_b']; 

Should make quay 3.13 works as quay 3.12.4.
