vtsls: Move all default configuration to workspace_configuration (#18259

) This fixes #18014 by fixing the regression that was introduced in #17757. In short: after digging into the `vtsls` code, it looks like it essentially doesn't need any `initialization_options`, it's all workspace configuration, since it tries to use the built-in settings from VS Code. I tested the completions, the inlay hints, the max memory - all of it now works after moving to `workspace_configuration`. Closes #18014. Release Notes: - Fixed `vtsls` being initialized the wrong way, which would mean the wrong options were used to enable completions or inlay hints.
