This is coming out of advice from https://securityscorecards.dev/viewer/?uri=github.com/carbon-language/carbon-lang Updates action versions and pins by checksum. This is something we already do in other places, and doing it with actions just seems consistent. Trying to add token permissions at the same time. step-security/harden-runner is being set up to monitor network traffic for actions, with the idea that we'd set it to block unexpected traffic in the future. Note, https://app.stepsecurity.io/secureworkflow generates the pinned checksums and adds the harden-runner. In some cases it added token permissions, but we have a couple it doesn't recognize (`gh` executions, other custom commands, jlumbroso/free-disk-space, reviewdog/action-setup as examples) so I'm trying to guess my best. Because these are workflows, testing is limited.
