Fix vsce publish (#11122)

### WHY are these changes introduced?

VS Code extension is failing to publish due to duplicate files. Fixes
#10654

### WHAT is this pull request doing?

To resolve this I have:
- [x] Updated dependencies
- [x] Ran `vsce ls` to see what files are included and updated
`.vscodeignore` to have the correct files
- [x] Ran `vsce package` and tested the built extension locally
- [x] Ran `vsce package` in CI to test that it builds correctly in CI
- [x] Removed test from GitHub action as there are no tests for the
extension
- [x] Removed unused `InitializeParams` code
