fix(vale): improve spelling and heading rules for Google style compliance

Spelling improvements:
- Exclude fenced code blocks (~code) and inline code (~raw) from checking
- Add filters for URL paths, full URLs, and shortcode attributes
- Prevents false positives on code syntax and API endpoints

Capitalization improvements:
- Add InfluxDB product exceptions (InfluxDB, InfluxQL, Telegraf, etc.)
- Add common technical acronyms (API, CLI, SQL, HTTP, JSON, etc.)
- Add cloud provider names (AWS, GCP, Azure, S3)
- Add link to Google style guide for sentence case headings

Aligns with Google Developer Documentation Style Guide:
