Pin vscode version in CI for windows (#2901)

We had already pinned the version for mac and Linux:
#2878 but it appears
that we have the same problem on windows its just crashing with error
code 0 which means our test runner wasn't signalling the failure.


Test run crashes on windows with false negative.

It appears that it's `vscode.window.showTextDocument` in our
`openNewEditor` utility that causes this. It's not always on the same
test case. By default it crashes in the scope tests, but if I disable
the scope test the same error occurs in our recorded tests that of
course uses the same `openNewEditor` function. I can't recreate this
locally. Looks like a memory leak or similar.
