The API for the beta projects has changed

[zadjii-msft]

As of June, the "new projects" have been officially taken out of beta. This also resulted in some changes to the graphql API surface:

1. The introduction of new ProjectV2 object and mutations.
2. The deprecation of ProjectNext object and mutations, scheduled for 1st October 2022.

I suspect a bunch of queries in Functions/Public/Projects will need to be updated to accommodate these changes.
