aetest fails with gcloud 468.0.0 or later

[sg0hsmt]

aetest always seems to fail if gcloud is 468.0.0 or higher.

The latest version of dev_appserver.py does not support for runtimes that reached end of support ¹.
However, I think aetest is failing because it specifies go111 as the runtime ².

reproduction code (Go 1.21).

go.mod:

module github.com/sg0hsmt/aetest

go 1.21

require google.golang.org/appengine/v2 v2.0.5

require (
	github.com/golang/protobuf v1.5.0 // indirect
	google.golang.org/protobuf v1.30.0 // indirect
)

main.go:

package main

import (
	"google.golang.org/appengine/v2"
)

func main() {
	appengine.Main()
}

main_test.go:

package main

import (
	"testing"

	"google.golang.org/appengine/v2/aetest"
)

func TestInstance(t *testing.T) {
	inst, err := aetest.NewInstance(nil)
	if err != nil {
		t.Fatal(err)
	}
	t.Cleanup(func() { inst.Close() })
}

aetest with gcloud 467.0.0 (success).

All AppEngine gen1 runtimes support has been removed.

https://cloud.google.com/sdk/docs/release-notes#46800_2024-03-12

If you still want to use Gen1 runtimes, you can use a frozen devappserver zip file that contains the old code:
