Fix Vale style warnings across documentation

[mintlify]

Summary

This PR addresses Vale style warnings identified across merged PRs from the past week by fixing style issues in English documentation files.

Changes made

• Capitalization fixes: HotJar to Hotjar, Expandables to Expandable components
• Heading sentence case: Get your Launch URL to Get your launch URL
• Terminology consistency: file path to path, blockquote to block quote
• Protocol case: http/https to HTTP/HTTPS
• Heading verbs: Imperative mood for action headings

Notes for human review

Some Vale warnings were not addressed because fixing them would require content changes beyond style corrections:

• Passive voice warnings are often appropriate in documentation context
• First-person pronouns are intentional in example prompts
• Acronyms like RSS, SSO, TLS are standard technical terms
• Some future tense usage is appropriate for describing system behavior

Note

Low Risk
Docs-only wording and heading changes with no product logic, configuration, or API behavior impact; risk is limited to potential minor wording regressions.

Overview
Applies a set of style-only documentation edits across multiple MDX pages to address Vale warnings: normalizes capitalization/branding (e.g., HotJar → Hotjar), refines terminology (e.g., “file path” → “path”, “blockquote” → “block quote”), and tweaks phrasing for clarity.

Standardizes headings toward sentence-case and imperative verbs (e.g., “How to Connect…” → “Connect…”, “Set up…” → “Configure…”), and makes minor technical wording consistency fixes (e.g., http/https → HTTP/HTTPS, Cloudflare “Worker” casing).
