pkg(go-1.20.1): Add Go 1.20.1

[e-sp]

user@work ~/s/piston (update-golang)> ./piston run go -l 1.20.1 packages/go/1.20.1/test.*
== Run ==
STDOUT
OK

[e-sp]

Apparently the test failed due to restraints of its environment:

Running packages/go/1.20.1/test.go with runtime=go
== Run ==
STDERR
# math
    runtime: failed to create new OS thread (have 3 already; errno=11)
    runtime: may need to increase max user processes (ulimit -u)
    fatal error: newosproc

Since test.go basically only contains "hello, world", would it make sense to rerun the test? Or do I need to change something?

package main

import "fmt"

func main() {
	fmt.Println("OK")
}

@HexF anything I can or should do?

Might need to up the run timeout for tests to pass
