chore: update Python version references from 3.9 to 3.10

[AdriiiPRodri]

Context

Python 3.9 is no longer supported (pyproject.toml defines requires-python = ">=3.10,<3.13"), but multiple documentation files and CI workflows still referenced it.

Description

• Updated all documentation and agent config files that incorrectly referenced Python 3.9 as the minimum supported version to 3.10
• Removed Python 3.9 from the CI test matrix in sdk-code-quality.yml and sdk-tests.yml
• 9 files updated across docs, AGENTS.md, README.md, skills, and GitHub Actions workflows

Not changed (intentionally):

• poetry.lock / uv.lock — third-party package requirements
• prowler/CHANGELOG.md — historical entries
• contrib/ — legacy deployment scripts (v2/v3)
• Test files with python3.9 Lambda runtime — valid AWS runtime
• Compliance JSON mentioning python3.9 — AWS Lambda supported runtimes
• CloudShell docs — factual reference to AL2023 environment

Steps to review

1. Verify all updated files now reference Python 3.10 instead of 3.9
2. Confirm CI matrix no longer includes 3.9
3. Confirm no other tracked files still claim 3.9 support
