Describe the problem you'd like to have solved

Working with node 21.5, but noted that this package is not supported

Describe the ideal solution

Consider support for node 21.5

Alternatives and current workarounds

downgrade to most recent 20.x version

Additional context

Would be nice to have, but workaround exists.

I wonder what use case would justify a non-LTS node version to be supported, since those version are not intended for production use.

We also have node 22 out, so it would be nice to address it also.

[codespearhead]

My last comment still holds: non-LTS are not meant to be used in production, so using them for any purpose other than developing Node itself is bad practice in the first place.

If you have different requirements that might justify it, please make a case for it.

Since 21.5 seems contentious, I opened a new issue for 22 which is an even-numbered LTS release.
