Incorrect go version requirement

[criadoperez]

Documentation here specifies the minimum go version is 1.19 but is in fact 1.20

$ go build -o libp2p-node

/home/alejandro/go/pkg/mod/github.com/quic-go/quic-go@v0.38.1/internal/qtls/go_oldversion.go:5:13: cannot use "The version of quic-go you're using can't be built using outdated Go versions. For more details, please see https://github.com/quic-go/quic-go/wiki/quic-go-and-Go-versions." (untyped string constant "The version of quic-go you're using can't be built using outdated Go...) as int value in variable declaration
note: module requires Go 1.20
