Update egglog to 1.0.0

[noahhuck]

Updates egglog to the 1.0.0 release. Some changes to the nightly script to make sure that the Cargo version is high enough.

The PR is good but one thing I want to mention is, the default backend isn't egglog, it's egg. So we're not actually running egglog in nightly. If you're certain the output works unchanged I guess I can handle that but maybe you want to temporarily add --enable generate:egglog as an argument to the nightly script, so we can test the egglog backend.

Good point, I was just making sure nightly worked as before. I did some local testing but I'll run a nightly with that enabled to get better coverage.

Great, should be enough to just add that flag to the makefile temporarily

Nightly is good, please undo the command switch but after that go ahead and merge.
