If we want to 100% make sure this works, we can fast-track it, close #40908, and let this open a PR.

This lgtm, but it was mostly the next part of the message that I was interested in automating:

codebytere last attended a TSC meeting in September 2020. gabrielschulhof last attended a TSC meeting in May 2021. Neither have participated in recent votes.

OK, I think this does something like that now. (I haven't tested it via an Action yet, but will run it when it lands and revise if necessary.)

The only nit would be to get rid of the " (maybe using fromJSON? not sure); other than that, LGTM.

I wonder if spaces aren't a problem in single-line GITHUB_ENV entries and we can just remove the quotation marks there.

I don't know for GITHUB_ENV, but when using ::set-output quotes are not needed: https://github.com/nodejs/node/pull/40845/files#diff-f9aa500b86b242f58f185509ad323b3526cf5effc683df4b5cb4d78df4108c5fR15-R16

And if all else fails, we can use the multi-line HEREDOC format they support which doesn't require quotation marks or other punctuation around spaces.

(Testing now on my fork.)

Yup, leaving out the quotation marks worked. https://github.com/Trott/io.js/runs/4318829465?check_suite_focus=true (The failure is because I didn't set a needed token on my fork.)

PR coming momentarily.
