feat: adds Language Server ID column to LS tables in preference pages

this looks a bit like a debug feature, doesn't it? Should the servers not have a name which is good enough for the user to understand which one is which one?

[sebthom]

Yes it is primarily a debug feature, same as the existing toggles to enable/disable Log language server communications to file. I find it quite useful to know what is contributed effectively from where. Same like when you go to Help>About>Installation Details>Plugins to see the plugin ids and not just the names. It might even be that the LS names don't have to be unique so you could have to entries with the same name.

Alternatively I can also display the ID in a hovering tooltip. I really would like to see the ID somewhere.

[rubenporras]

Yes, I think that a tooltip would be better.
