Can WorkspacesRemove optionally ask whether I really want to remove a workspace?

[sluedecke]

I am still a NeoVim noob and this might just be something I need to get better used to. But by calling WorkspacesRemove without argument I removed the current workspace. While this is fine as behaviour, what I really wanted is to remove a different workspace by name. My fault. Repeatedly ...

I kindly request to consider adding a safety question to WorkspacesRemove just for this case and just for the sake of stopping one from deleting stuff accidentially.

Hi there!

I'm really not doing anything to maintain workspaces.nvim anymore because I no longer use it.

If you happen to work on this I'm more than happy to review and merge it in though!
