dev_appserver.py doesn't support go122

[tarasmadan]

Is your feature request related to a problem? Please describe.
We can't update google.golang.org/appengine/v2 anymore.

The new vendor/google.golang.org/appengine/v2/aetest/instance.go requires go122 instead of go111.

As far as I see, dev_appserver doesn't support it:

RuntimeError: Unknown runtime 'go122'; supported runtimes are 'custom', 'go', 'go111', 'go112', 'go113', 'go114', 'go115', 'java', 'java7', 'java8', 'php55', 'php72', 'php81', 'python', 'python-compat', 'python27', 'python310', 'python37', 'python38', 'python39'.

Error details are here.

"./tools/syz-env dev_appserver.py -h" claims:

...
--runtime RUNTIME specify the default runtimes you would like to use.
Valid runtimes are ['java', 'php81', 'php55',
'python', 'php72', 'python27', 'java7', 'custom',
'go111', 'python-compat', 'go113', 'go112', 'go115',
'go114', 'python310', 'go', 'python37', 'python39',
'python38', 'java8']. (default: )
...

Update containerized dev_appserver.py to support go122?

Tried Cloud SDK 475.0.0 (latest).
Our tests crash with the next error:

It routed me to the https://b.corp.google.com/issues/329705717?pli=1 .
We can use version <468.0.0 or wait for this bug resolution.

Go 1.22 runtime support was added in 465.0.0.

[tarasmadan]

Tested version 467. Runtime go122 is not supported! :)

[tarasmadan]

And yes, the problem starts with version 468. The alternatives are the local patch or to wait for the bug resolution.
