also need to add to flavor array above

We can remove this one; I'm trying to keep only a single entry for typescript@next. I suspect that github actions throttle if you use it too much, so I try to keep the test matrix small where possible.

I renamed this PR to clarify that it does not add support for node 20, it only adds the @tsconfig/bases for node 20.

@cspotcode So when will ts-node support node v20, my projects are currently in a standstill due to this

[cspotcode]

CI is showing "Error: Unable to find Node version 'nightly' for platform linux and architecture x64."
https://github.com/TypeStrong/ts-node/actions/runs/4972785977/jobs/9240373078?pr=2003

The version was 20-nightly and this PR changes it to nightly. Perhaps it should be changed back?

Should there be a release newer than a year ago that makes mention of Node20?
