The Go command can auto-update now

starting with Go 1.21, the go command has built-in toolchain updating functionality (like nvm or rustup but without needing a separate tool).

Today you can set:

go env -w GOTOOLCHAIN=go1.21.1+auto

And it will download Go 1.21.1 (if you haven't already) and use that as the default toolchain. When you want to update to 1.21.2 (or 1.22 later on) just update the go env -w command, no need to download and install the Go binaries again.
