[Task][GoSDK]: Update Min Go version to 1.20
What needs to happen?
Allow the Go SDK to adopt features of the standard library in Go 1.20. In particular, prism uses the pre-standard library version of slog which requires compiling with go 1.20.
Since slog will be available in the standard library with go 1.21's release next month, we'll update to that relatively quickly as well.
See #24789 for other work related to replacing the direct runner with prism.
