[PATCH 1/3] scripts/container: Turn runtimes class variable into a tuple

[Nathan Chancellor <nathan@kernel.org>]

'ruff check --select RUF scripts/container' warns:

  RUF012 Mutable class attributes should be annotated with `typing.ClassVar`
     --> scripts/container:108:16
      |
  106 |     """List of all supported runtimes"""
  107 |
  108 |     runtimes = [PodmanRuntime, DockerRuntime]
      |                ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
  109 |
  110 |     @classmethod
      |

runtimes is never modified so move from a list to a tuple, clearing up
the warning.
