Add regression test for type check warnings

[VenelinMartinov]

This adds a regression test for the warnings we issue to users when a property has the wrong type. This could result in panics down the line, so we need to catch them early.

Testing this in the bridge is currently quite hard as we can't use YAML for this because it is too strict in type-checking. We only have unit tests which indirectly test this but these break under PRC.

This was introduced in pulumi/pulumi-terraform-bridge#1987
original GCP issue: pulumi/pulumi-terraform-bridge#1979

Bridge issue for integration tests for the feature: pulumi/pulumi-terraform-bridge#2418

Looking good! No breaking changes found.
No new resources/functions.

Can we add a bit of context what "panics down the line" means? What is the scenario we're trying to catch with this test? We currently catch upstream panics and issue warnings, so I'm curious what other type of panic we'd like to prevent, or maybe I'm just misreading here.

When this test fails, does it point at a type checker bug regression in the bridge?

Test itself looks reasonable.

[VenelinMartinov]

Yeah, I meant that the TF provider might panic if passed wrongly typed input, so we catch TF panics if a type mismatch occurs and issue a sensible warning.

When this test fails, that does point to a regression in the bridge. Ideally we'd pull this in the bridge and I've opened pulumi/pulumi-terraform-bridge#2418 for that.
