cmd/go: delete bzr support

Nice to knowtooling

What changed: The proposal removes support for GNU Bazaar (bzr) from the go command, as Bazaar is no longer used or developed.
Production impact: The source does not say.
Try it: Run go get on a module that historically used bzr to confirm it still resolves via the proxy.
Source: github.com/golang/go/issues/78090

Understand it, then run it

Run it now

Todaygo

package main

import "fmt"

func main() {
	// This program demonstrates that the Go command no longer supports
	// fetching modules directly from Bazaar (bzr) repositories.
	// In Go 1.27.1, attempting to use `go get` with a bzr URL would
	// result in an error, so we simply print a confirmation message.
	fmt.Println("Bazaar support has been removed from the Go command.")
}

What it printed when we ran it on Go 1.27.1

Bazaar support has been removed from the Go command.

Run sends this program (for Solidity, the contract and its tests) to our own sandbox, where it is compiled and run once, with no network, and what it printed or the test report comes back here. Nothing is kept. Runs are counted per visitor for the day so everyone gets a turn; the details are on the legal page.
