Test with several Vim and Neovim versions and fixed deps

Run tests on GitHub Actions with Vim 8.2.0000, the latest Vim, Neovim
0.9.5 and the latest Neovim by rhysd/action-setup-vim. test/run.sh only
uses the editors in $VUE_TEST_EDITORS if set, and fails if none runs.

Clone the syntax plugins for tests at fixed commits, so changes there
don't break tests unexpectedly.
