RHIDP-9751 - fixed broken links

[themr0c]

• Added more ignored links to avoid warnings for redirections that we cannot avoid in the Customer Portal, and pollute the output.
• Deactivated invalid links.
• Fixed broken external links.
• Fixed broken cross-title links.
• Fixed links to use attributes where relevant.
• Use attributes where relevant.
• Sorted attributes alphabetically for maintainability.
• Disambiguation for the Red Hat Ecosystem Catalog vs. Red Hat Container Registry (one link was failing, but multiple mentions were inconsistent => consistently named across the board).
