Jon Ross-Perkins 97816a3598 Use https://app.stepsecurity.io/secureworkflow to improve workflow security. (#3879)
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.
