Webapp: support only const in OneOf as default value

[marcosmarxm]

Tell us about the problem you're trying to solve

The Webapp doesnt support to use only const in the spec.json to create a new connector.

See example from Google Search Console:

airbyte/airbyte-integrations/connectors/source-google-search-console/source_google_search_console/spec.json

Lines 27 to 79 in 9aa5a5a

@marcosmarxm is this only related to the list of objects?
let's say I have a drop-down of possible values or a list of values, where each can be one of the choices.
The current limitation of web app looks unjustified, IMO connectors shouldn't depend on low layer (UI 3rd party).

I checked the docs here (https://docs.airbyte.com/connector-development/connector-specification-reference), but it doesn't have any details.

I have checked - all works with const only keyword now

there is also closed issue with improved SAT test #11703 which checks const only keyword in common properties

@marcosmarxm I think we can close this issue now
