These still work for older versions of deno?

Yes, cache has been supported for long time. the deno install is actually the new one that wouldn't work. Plus it would still want entrypoint, or deno.json

Start command should work in all versions too. Ther is no version-specific override for Deno start command: https://github.com/open-runtimes/open-runtimes/tree/main/runtimes/deno/versions
