fix(ci): pin third-party actions to full commit SHAs

The account's Actions policy requires a full-length SHA ref. A tag or branch ref is refused at
startup — startup_failure, no jobs, "this workflow graph cannot be shown" — so these workflows
could not run at all. This resolves each ref to the commit it currently points at and records the
ref in a trailing comment, e.g. actions/checkout@<sha> # v4.

dtolnay/rust-toolchain takes its toolchain from the ref itself, so those steps also gained an
explicit with: toolchain: input; without it, a SHA ref would silently lose the channel.

No behaviour is intended to change beyond the pins.

`dtolnay/rust-toolchain` takes its toolchain from the ref itself, so those steps also gained an
explicit `with: toolchain:` input; without it, a SHA ref would silently lose the channel.

📝 Summary

Summary by CodeRabbit

  • Chores
    • Pinned the workflow’s repository checkout action to a specific version for more consistent and reliable automation.

Walkthrough

The rhodibot RSR compliance canary workflow now references actions/checkout by commit SHA instead of the mutable v7.0.1 tag. The workflow behaviour remains unchanged.
