GH-14927 : [Dev] Crossbow submit does not work with fine grained PATs

[assignUser]

The old variant with token passed as name does only work for classic PATS, passing the token as password works for both classic and fine grained PATs.

I have tested myself. With my previous non-fine grained token I was able to submit a crossbow task with both using token as user and password.
With a new fine-grained token it only worked using the token as a password. Otherwise I got the following error:

archery.crossbow.core.CrossbowError: Wrong oauth personal access token
