Fix RHEL 8 repository names for perl-IPC-Run package installation across all variants

[Copilot]

The postgresql_role resource was failing on RHEL 8.10 with an "Unknown repo: 'powertools'" error when attempting to install the perl-IPC-Run package dependency required for the PostgreSQL pg gem.

Problem

The issue occurred in libraries/sql/_connection.rb where the code was trying to install perl-IPC-Run from the powertools repository:

options('--enablerepo=powertools')

However, the powertools repository doesn't exist on RHEL 8 systems, causing the package installation to fail and breaking the postgresql_role functionality.

Solution

Updated the code to use platform-specific repository names for different RHEL 8 variants:

case node['platform']
when 'oracle'
  options ['--enablerepo=ol8_codeready_builder']
when 'redhat'
  options('--enablerepo=codeready-builder-for-rhel-8')
else
  # CentOS Stream, AlmaLinux, Rocky Linux use powertools
  options('--enablerepo=powertools')
end

This ensures each RHEL 8 variant uses its correct CodeReady Builder repository:

• RHEL: codeready-builder-for-rhel-8
• Oracle Linux: ol8_codeready_builder
• CentOS Stream, AlmaLinux, Rocky Linux: powertools

Impact

• ✅ Fixes postgresql_role functionality on RHEL 8.10 and other RHEL 8 variants
• ✅ Maintains compatibility with CentOS Stream, AlmaLinux, and Rocky Linux
• ✅ No impact on RHEL 7 (uses different repository configuration)
• ✅ No impact on RHEL 9 (already uses correct crb repository)
• ✅ Preserves Oracle Linux support with platform-specific repositories

This change provides comprehensive support for all RHEL 8 variants by detecting the specific platform and using the appropriate repository name.

Fixes #783.

@copilot This is only correct for RHEL, powertools is required for centos-stream, almalinux and rocky.

[Copilot]

You're absolutely right! I've updated the code to handle all RHEL 8 variants correctly. The new implementation uses case node['platform'] to detect the specific platform:

• RHEL: codeready-builder-for-rhel-8
• Oracle Linux: ol8_codeready_builder
• CentOS Stream, AlmaLinux, Rocky: powertools (restored for these platforms)

This preserves the original powertools repository for CentOS Stream, AlmaLinux, and Rocky Linux while fixing the issue for actual RHEL systems. Commit: 1adde8a
