Git 2.23.0-rc0 HTTP authentication failure - error message change

Hi,

I've run 2.32.0-rc0 through the Bitbucket Server test matrix and it picked up a
change in error message that perhaps is unintentional.

On 2.31.1:
  $ git ls-remote http://notauser@localhost:7990/bitbucket/scm/project_1/rep_1.git
  Password for 'http://notauser@localhost:7990':
  fatal: Authentication failed for 'http://localhost:7990/bitbucket/scm/project_1/rep_1.git/'

and on 2.32.0-rc0:
  $ git ls-remote http://notauser@localhost:7990/bitbucket/scm/project_1/rep_1.git
  Password for 'http://notauser@localhost:7990':
  fatal: unable to access 'http://localhost:7990/bitbucket/scm/project_1/rep_1.git/': The requested URL returned error: 401

This appears to be a side effect of 1b0d9545bb8, if I revert that commit the old
behavior returns. Certainly we can update our pattern matching to match the new message,
but I wonder if the old message is preferred for folks who are not familiar with HTTP
status codes.

Best Regards,
