build(elrond-go): Build with Go 1.17 to fix issue with quic-go

Elrond-Go's CI uses Go 1.17 specifically [0]. When using the `buildGoModule` Nix
function we're asking Nix to build with the latest `go` package version, which
at the time of writing is 1.19 [1], however `quic-go`, which is a dependency of
Elrond-go, does not yet support Go 1.19 [2].
