Subject: [PATCH] Use the Go toolchain installed by actions/setup-go

Since version 1.21, Go may automatically download a different version of Go.
Disable this behavior so that entire pipelines use only one version.

The "go" and "toolchain" directives indicate the minimum version of Go
required when importing and developing the module, respectively. We are
concerned only with compatibility, so downgrade "toolchain" to 1.22.0.

Issue: PGO-1898
See: https://go.dev/doc/toolchain
