feat: add GitHub pull request template

Add practical PR template tailored to docs-v2 monorepo structure and workflow. Template includes emoji headings matching Auth0 conventions, dedicated redirects section, references to authoring guidelines, and polite collaborative language.

Key features:
- Emoji headings (✏️ 📁 🔗 ✅ 🔄 📊 🚀 📝 💬) matching Auth0 style
- Redirects section with guidance and JSON example (critical given 4,201+ existing redirects)
- Link to .claude/skills/writing-auth0-docs/SKILL.md authoring guidelines
- References section for Jira tickets and product specs
- Polite, collaborative tone throughout instructions
- Mintlify-specific validation commands (mint dev, mint broken-links, mint a11y)
- No feature flag references (not applicable to public docs repo)
