No support for Rego.v1

[perithompson]

When trying to integrate conftest into atlantis policy-checks I am encountering errors when writing policies as per the conftest documentation, this seems to be due to a lack of support for rego.v1

rego_parse_error: if keyword is required before rule body

>> conftest --version    
Conftest: 0.56.0
OPA: 0.69.0

Please could we have updates to how to use conftest with rego.v1 and have some documentation on how exceptions and denies work when importing rego.v1 instead so that the contains and if keywords are used

As a starting point, we have a guide here for projects integrating with OPA's go packages here: https://www.openpolicyagent.org/docs/latest/v0-upgrade/#upgrading-for-go-integrations. I am about to close up my working week here, but @ me if I can help at all here.

I will look into bumping Conftest's dependency to Rego v1 soon. It does have breaking changes, so we'll likely need to update the examples, docs, etc.

@perithompson In the interim, you can add import rego.v1 to your Rego policies and update them with V1 syntax. This has been supported since OPA v0.59 https://docs.styra.com/regal/rules/imports/use-rego-v1#rationale.
