SEC-090: Automated trusted workflow pinning (2023-04-03)

[hashicorp-tsccr]

Hello,
This PR was auto-generated to pin the Actions workflow files in this repository to use trusted SHAs.
This is in support of RFC SEC-090 which is due to be implemented by EOQ2 FY24.

Please do the following:

• Approve and merge this PR if you are happy with the changes.
• Check if there are any untrusted third-party Actions in the workflow files and onboard them to the TSCCR.
• The yaml comment "# TSCCR: no entry for repository " in the workflow files identifies an untrusted Action.
• If you have to onboard any third-party Actions, update and pin your workflows using the tsccr-helper tool after the Actions have been onboarded OR reach out to #team-prodsec and we can run this automation again.
• Verify that your Actions are still working as expected after pinning.

Please reach out to #team-prodsec if you have any questions.
