[ci] switch to a new personal access token

[danking]

I created @hail-ci-robot, created a personal access token with the "resource owner" set to "hail-is". It has permission to read and write pull requests and statuses. The token expires in just under a year. I created a calendar event on Hail General Calendar to remind us to rotate it.

I'm a bit perplexed why other keys changed. This is the setting for the non-secret keys.
