[BUG] Update the premerge and nightly tests after moving the UDF example to external repository

[res-life]

Describe the bug
After this PR NVIDIA/spark-rapids-examples#94 is merged, should update the premerge and nightly tests accordingly.

Seems it's rapids_build-it-UDF-native.

Then we can merge this PR #4619.

Steps to run UDF examples including native tests:

git clone spark-rapids-examples
cd examples/RAPIDS-accelerated-UDFs
mvn clean verify -Pudf-native-examples

@res-life did you mean to reference #4619 instead of #4408? In either case, the PR that will break the nightly builds should be marked as a draft to prevent it from being accidentally merged even after it is approved until the nightly builds are ready for it to be merged.

[res-life]

Yes, referenced the wrong PR, updated.

Nightly pipeline against the new repo is ready, will remove the udf-examples source from spark-rapids GitHub, and update the old premerge/nightly jobs removing mvn build on udf-examples

[NvTimLiu]

nightly pipeline created : examples-udf-examples-nightly, examples-udf-examples-native

[res-life]

I've checked the pipelines, all are passed, so close this issue.

I thought the intent of this issue was to update the premerge check of this repository, so that PRs proposed for the spark-rapids repository are tested against the udf-examples tests in the spark-rapids-examples repository. Having separate nightly tests is fine, but it would be nice to not lose the UDF testing in the premerge.
