Release with CD failed with "Support for password authentication was removed" although PAT is used

[szpak]

The release of 1.15.0 on CI failed with:

> Task :pushRelease2
Caching disabled for task ':pushRelease2' because:
  Build cache is disabled
Task ':pushRelease2' is not up-to-date because:
  Task has not declared any outputs despite executing actions.

What's interesting, the token should be used there and in addition, releasing that way succeeded on 2022-11-27, way after the mentioned "August 13, 2021". Even the recent change with enforced 2FA should not affect that comment as PAT is configured.

To be explained. Manual releasing is very unpleasant :-/.
