feat: update lsp_types to the latest version

[aminya]

• feat: update lsp_types to the latest version:
  • This required adding some optional fields
  • Updating the progress reporter
  • Using u32 in some places instead of u64
  • Passing the correct type as the request/response
  • Changing the enum field cases to upper case

After debugging the code for some time, I cannot find the reason why the 9 remaining tests are failing. Any help would be appreciated.

using this in the find_impls test seems to fix the issue, but modifying the tests like this looks random to me.

                work_done_progress_params: WorkDoneProgressParams {
                    work_done_token: Some(NumberOrString::String("progress_1".to_owned())),
                },

Just a heads up that this is unlikely to get any eyes or be merged because RLS is being deprecated in favor of Rust Analyzer
