Update Dockerfile.rhel11 base image from ubi10 to ubi11 once ubi11 images are available

[coderabbitai]

Background

In tests/failures/check/v0/Dockerfile.rhel11, the base image is temporarily set to ubi10/s2i-core because ubi11 images are not yet available.

Once UBI 11 images are published, this file should be updated to use FROM ubi11/s2i-core instead.

File to update

• tests/failures/check/v0/Dockerfile.rhel11
