DevOps: add libicu-devel to Rocky Linux build images

Add libicu-devel package to Rocky Linux 8, 9, and 10 Dockerfiles
to provide ICU (International Components for Unicode) library
support required for PostgreSQL 16 kernel compilation.

This dependency is already present in Ubuntu 22.04 and Ubuntu 24.04
development images, ensuring consistency across all supported build
platforms for PostgreSQL 16 compilation requirements.
