.github: pin actions/setup-go usage to latest 5.x (#13553)
Pin actions/checkout usage to latest 5.x. These were previously pointing
to `@4` which pulls in the latest v4 as they are released, with the
potential to break our workflows if a breaking change or malicious
version on the `@4` stream is ever pushed.
Changing this to a pinned version also means that dependabot will keep
this in the pinend version format (e.g., referencing a SHA) when it
opens a PR to bump the dependency.
The breaking change between v4 and v5 is that v5 requires Node 20 which
should be a non-issue where it is used.
