Implement optional version argument into VerdiCommand that specifies when a deprecated command is removed

[agoscinski]

Is your feature request related to a problem? Please describe

In PR #6426 we implemented into the deprecation command decorator the version argument that allows to specify with which version a command is removed from the code base. But since the deprecation command decorator became deprecated (see replacement PR #6433, see deprecation PR #6461) we did not need it. I kept the feature in a backup PR #6462 to implement it properly in aiida.cmdline.groups.VerdiCommand.

Describe the solution you'd like

Most likely we need a new input argument in aiida.cmdline.groups.VerdiCommand that specifies the version of removal, but I keep the design as open to discuss.
