chore: manage tool versions in go.mod (#21455)

Go 1.24 adds [tool
dependencies](https://go.dev/doc/modules/managing-dependencies#tools).
This allows us to track versions of tools in our `go.mod` instead of
sprinkling various `go run` commands throughout our codebase.

NOTE: there are still various hard-coded `go install` commands in our
dogfood Dockerfile. As that list is likely severely outdated, will leave
that for a separate PR.
