docs/INSTALLATION.md implies the latest Vim should be installed. https://formulae.brew.sh/formula/vim installs vim 9.x, but currently the CI (possibly the test runner too?) uses Vim 8.2 because GHA's ubuntu-latest is Jammy Jellyfish (22.04). Therefore, it'll be a while before the CI will be on 9.x so we should clarify the supported Vim version in that document for students working offline. That'll avoid any issues where the student might run code that's not supported in 8.x.
I don't think this is needed any more since the CI runs off the official Vim repo so it's always up-to-date. The test runner image is similarly based on Alpine Linux so we're running Vim 9.x.
