CICD releases aren't setting the pre-release flag correctly in Github's release action

[daxpryce]

We release on merge/push to dev or main. If on dev, we want the prerelease flag to be set - we also pick a version number that indicates a pre-release to PyPI.

I thought we were doing that, but it seems to be not working. As it is now I'm constantly marking it as pre-release after the fact and I'd prefer I didn't have to do that. At the least set it to true at all times and I'll manually set it to false later.

So I thought I had fixed this, but it still seems like the prerelease flag is just straight up ignored. I can conditionally run an action depending on branch and hardcode the true/false but it's galling that I have to.

I hate trying to track down CICD issues >.<
