Don't ignore gitkeep files for ark-infra

It was pointed out the the riscv kabi-module directory was missing because it only had a .gitkeep file which is ignored as a '.*' file in .gitignore. Add an entry to redhat/.gitignore to not ignore .gitkeep files.

While at it, cleanup redhat/scripts/ci/ark-create-release.sh to include Kconfig.redhat in the ark-infra branch and remove the gitkeep note as it is fixed now.

I updated ark-infra branch manually, so it is already resolved. This helps make sure it doesn't break again.
