Repos in the same org not able to run `gh stack submit`

[parkerholladay]

Last Friday, I was testing stacked PRs for our org, and I was able to submit two stacked PRs in repo-a. This week, I am able to submit stacked PRs in repo-b and repo-c within the same org, but not in repo-a. I am getting the error:

$ gh stack submit
Checking stack state...
⚠ Stacked PRs are not enabled for this repository
? Would you still like to create regular PRs?

I tried the following API calls to diagnose:
gh api -i 'repos/MyOrg/repo-b/stacks?per_page=1' - returns 200
gh api -i 'repos/MyOrg/repo-a/stacks?per_page=1' - returns 404

gh: 2.97.0
gh-stack: 0.1.0

I disabled Require merge queue in the repo rulesets on repo-a, and I was able to push a stack again. So, my first stack must have been before enabling that rule, and it feels like this is related to #349
