Document go 1.22 and golangci-lint 1.56 requirements (#172)

TL;DR: Due to an incompatibility with go 1.23 and a dependency of
abigen, devs must explicitly install go 1.22 (ex: using brew install
[email protected]) and golangci-lint 1.56.

xmtpd requires abigen which uses memsize. memsize relies on access to
`runtime.stopTheWorld` and `runtime.startTheWorld` [1] which was OK in
go 1.22 and forbidden in go 1.23
