Add annotation test for $dynamicRef resolving to $dynamicAnchor

[Anshikakalpana]

The annotation tests in core.json cover $ref resolving through $defs, verifying that annotations from the referenced schema are attributed to the referenced location.

I couldn't find an equivalent test for $dynamicRef resolving to a $dynamicAnchor, since both are part of the core 2020-12 vocabulary and appear to have the same annotation attribution behavior once the reference resolves.

I verified this using the annotation harness, which produced:

{ 'https://json-schema.org/keyword/title': [ 'Foo' ] }

Schema used:

{ "$dynamicRef": "#foo", "$defs": { "foo": { "$dynamicAnchor": "foo", "title": "Foo" } } }

Would a PR adding this test be welcome?

You're right, dynamic references do seem to be missing. The example you gave is good enough for simple test, but we'll also want an example where the dynamic reference resolves to a different location depending on the instance value.

Thanks! I can work on adding both a simple $dynamicRef annotation test and another example where the dynamic reference resolves to a different location depending on the instance value. I'll put together a PR once I have both examples ready.

Go ahead.

I was checking related cases in the validation suite to make sure my tests were complete, and noticed these gaps.
I found these while verifying my PR #862 implementation —

1. $dynamicRef resolving to a plain $anchor (not $dynamicAnchor)
2. $ref resolving to a $dynamicAnchor

Both exist in the validation test suite but have no annotation equivalent. Verified both using the harness.
Would you prefer I include these in the same PR or open separate issues?
