go tool support documentation

[ftqo]

Go has supported using go get -tool github.com/pressly/goose/v3/cmd/goose@latest since Go 1.24. I believe this may be the idiomatic way to use Goose in Go projects, and therefore the README should include it.

I'm not sure I agree it's the most idiomatic way. I have reservations about promoting this as the primary approach since it can lead to go.mod bloat when teams add tools as dependencies.

That said, given the native toolchain support and the likelihood that many people will use this method, you're probably right that the README should document it as an option alongside other installation methods.

After playing around with it a bit more, it may be better to use it with the -modfile flag. In my own project, I have a tools.go.mod. Then, to invoke goose, I have documented using go tool -modfile=tools.go.mod goose .... I definitely see downsides to this, but it does avoid the whole dependencies in the modfile issue.
