[Settings Cycler] Option to only modify workspace settings

[dimateos]

Hey! Thanks for the nice extensions :)

So there is overrideWorkspaceSettings to ensure settings are switched even when the workspace defines them.

Most cases I prefer to edit ONLY workspace settings instead of user ones, so I would love a new flag like setWorkspaceSettings to only edit the toggled setting for the workspace.

This way the user global config remains unchanged and only the workspace reflects toggled changes. Less diff for the settings sync when I only want to locally switch a setting (commonly temporally).

The extension basically already knows how to do it, but right now when overrideWorkspaceSettings is set it only writes to the local workspace settings when the settings key already exists. For this feature we would simply need it to emplace it anyway.

Regards!
