Update timing out on GitHub actions but running fine locally

### Description of the bug
I've been using the `expo-github-action/preview` sub-action successfully for about a month. The `eas update` command has always taken much longer in CI than when I run it locally, but I wasn't too concerned about it.

Recently, I submitted a PR which caused the preview step to time out completely, even though the logs suggest that everything went through successfully. Note the step time in the top right:

I've been able to use the same branch to run `eas update` locally with no problems.

### To Reproduce
I pushed a set of changes which caused the preview sub-action to stop working properly. It's hard to say which part of the changes could've caused it, since it was a decently-sized PR. These are my Expo dependency updates in case something stands out:

#### Expected behavior
I expected that the update would finish successfully as it has in the past.

#### Actual behavior
The update seems to have timed out, and there are no new updates in my Expo dashboard.
