What changes were proposed in this pull request?

This PR aims to mark SupportsPushDownVariants as Experimental instead of Evolving in Apache Spark 4.1.x.

Why are the changes needed?

During Apache Spark 4.1.0 RC2, it turns out that this new Variant improvement feature still needs more time to stabilize.

We had better mark this interface itself as Experimental in Apache Spark 4.1.0 while keeping it Evolving in master branch.

Does this PR introduce any user-facing change?

No.

How was this patch tested?

Manual review.

Was this patch authored or co-authored using generative AI tooling?

No.
