Rename `editor.action.triggerParameterHints` and `editor.action.rename` command capabilities

[Veykril]

          Same goes for the `"editor.action.triggerParameterHints",` capability. Thanks for calling that out I think we should move those over to `rust-analyzer.*` or similar. The names are based on the equivalent vscode commands but we should clearly not use the exact same names for those.
