[stable-2.9] bump hcloud version to 1.4.1 (#62097)

* bump hcloud version to 1.4.1

`hcloud`<=1.4.0 has requirement `requests==2.20.0`. This prevents the
installation of the Vcenter Automation SDK which depends on `requests>=2.22.0`.

`hcloud` 1.4.1 does not have the problem: 8bff356efb
Bumping the dependency will resolve the issue.
