Channel tabs fail schema validation

[BobGerman]

Describe the bug
Schema with a configurable tab fails validation even though it matches the schema and TDP created mainfest, and uploads manually

To Reproduce
Steps to reproduce the behavior:

1. Generate a static tab app in Teams Toolkit (no configurable tab template exists now?)
2. Add a configurable tab:

    "configurableTabs": [
        {
            "configurationUrl": "${{TAB_ENDPOINT}}/index.html#/tab",
            "canUpdateConfiguration": true,
            "scopes": [
                "groupChat",
                "team"
            ],
            "context": [
                "privateChatTab",
                "channelTab",
                "meetingSidePanel"
            ]
        }
    ],

3. Hit F5 and get this error:
   (×) Error: teamsApp/extendToM365 failed.
   (×) Error: Request failed with status code 400 (tracingId: 00-cdb92b92dc8ff464ab2bf54739c3e088-34de022eb82bf43b-00) BadRequest: Manifest is not valid: [
   "Value "groupChat" is not defined in enum. Path 'configurableTabs[0].scopes[0]', line 33, position 27.

I tried bumping the manifest schema to 1.17 but got the same error

Expected behavior
I expect the schema to validate in TTK just as it does in TDP and Teams itself

UPDATE: Both TDP and Docs are wrong - it is "groupchat" not "groupChat"
Not sure where to file bugs against these but TTK is right everyone else is wrong!
