test: Removes @vscode/test-electron (#114)

We were not using this test infrastructure, and after #56 it should be
better to accomplish these tests using something like playwright.

@vscode/test-electron is really not ideal. It's heavy, and does not
provide any tooling to test webviews, which we make use of.
