@jpkrohling I saw your comment on #37 and updated the script. Feel free to close if this isn't what you had in mind.

This looks about right! Thanks!

I've seen a failure when running the workflow manually, but it's likely unrelated to this PR:

jq: error: Could not open file latest-core.json: No such file or directory
date: invalid date ‘+%s’
jq: error: Could not open file latest-contrib.json: No such file or directory
date: invalid date ‘+%s’
./scripts/update-to-latest-otelcol.sh: line 48: ((: <  : syntax error: operand expected (error token is "<  ")

Are you on a mac? Running it locally on mac I had to make sure to use GNU date or I had the same error.

Linux, but this error came from the CI.

Ahh this might be a different error than I saw locally but now I'm curious, I'll look into it a bit later today.
