[codex] Fix certification review docs and metadata

[DNACENSolutions]

Type of Change

• Bug fix
• New feature
• Breaking change
• Documentation update

Description

Please include a summary of the changes and the related issue. Also, include relevant motivation and context.

Bug Fix: Address certification review feedback across collection packaging metadata, the root README, CVP documentation, and role metadata.
Root Cause (if applicable): requirements.txt was excluded from the built artifact, Automation Hub-facing docs still contained relative links and GitHub-first support guidance, many CVP docs still instructed users to install Ansible with pip, and role metadata still advertised min_ansible_version: "2.14" after the collection minimum moved to >=2.16.0.
Fix Implemented: Removed requirements.txt from build_ignore, aligned the root README license/support/release-notes guidance, converted bundled CVP and role documentation links to absolute GitHub URLs, updated certified-support wording to use Automation Hub Create issue, switched CVP install guidance to EE-friendly SDK-only examples, and raised all role min_ansible_version values to 2.16.

Enhancement: Improve certification readiness for published collection artifacts and bundled documentation.
Enhancement Description: Standardized user-facing guidance for certified content and removed documentation patterns that do not render or compose well on Automation Hub / Execution Environments.
Impact Area: README.md, galaxy.yml, CVP_GUIDE.md, cvp/**/README.md, and roles/**/meta/main.yml.

Testing Done:

• Manual testing
• Unit tests
• Integration tests

Test cases covered:

• ansible-galaxy collection build --force --output-path /tmp/cc-build-check
• Verified built tarball includes top-level requirements.txt
• ansible-test sanity --local --color yes $(git diff --name-only) from a temporary ansible_collections/cisco/catalystcenter layout
• Validated generated GitHub/raw documentation URLs resolve to repository paths

Ansible Best Practices

• Tasks are idempotent (can be run multiple times without changing state)
• Variables and secrets are handled securely (e.g., using ansible-vault or environment variables)
• Playbooks are modular and reusable
• Handlers are used for actions that need to run on change

Documentation

• All options and parameters are documented clearly.
• Examples are provided and tested.
• Notes and limitations are clearly stated.

Screenshots (if applicable)

Notes to Reviewers

• This PR is documentation/metadata-only; no controller or network deployment actions were performed.
• The unchecked Ansible Best Practices items are not applicable because no task or playbook execution logic changed.
• Unit and integration suites were not run because the changes are limited to documentation and metadata.
