Specify go compiler minor version (#563)

## What was changed?
Specify minor version of Go compiler

## Why?
It's now required. See golang/go#65568.
Without it on MacOS I get
```
go: downloading go1.22 (darwin/arm64)
go: download go1.22 for darwin/arm64: toolchain not available
```

## How did you test it?
`go mod tidy && go build -o temporal ./cmd/temporal/main.go`

go.mod
