9.0 Odd `RebasableToOtherWorkspaceInterface` commands `AddDimensionShineThrough` and `MoveDimensionSpacePoint`

[mhsdesign]

The commands AddDimensionShineThrough and MoveDimensionSpacePoint will implement the RebasableToOtherWorkspaceInterface via https://github.com/neos/neos-development-collection/pull/4708

but they are not interested about the wordspaceName unlike the other commands but still operate on the contentstream ids.

This is the reason for the quirky $targetContentStreamId in createCopyForWorkspace.

Both commands will be used for structure adjustments and MoveDimensionSpacePoint will be available via flow content:moveDimensionSpacePoint

Despite being a little quirky they are both declared public api, so it would be hard to fix their api after Neos 9

Proposal:

• make them internal and fix them later and (and createCopyForWorkspace)
• fix it now to operate only on workspaces
