fix(vscode): fix corrupted VS Code downloads in testing

'yarn test' downloads Visual Studio Code into a temporary directory. A
change in Visual Studio Code's server caused the download to break [1].
Example error message on Windows:

    Test error: Error: spawn
    P:\quick-lint-js\plugin\vscode\.vscode-test\vscode-win32-x64-archive-1.55.2\Code.exe ENOENT
    Exit code:   -4058

Fix the broken downloading by applying a patch to the download
script [2].
