Fix Vale style warnings across documentation

[mintlify-development]

Summary

This PR addresses Vale style warnings identified in CI checks from PRs merged in the last week.

Changes

Vale vocabulary updates:

• Added common tech acronyms to exceptions: REST, RSS, TLS, VPN, SLA, RBAC, OAS, GEO, WAF, UTC
• Added technical terms to vocabulary: hostname, allowlists, bot's, timeframe, impactful, unfixable, webtoken, noindex
• Made LLMs case-insensitive to accept both 'LLMs' and 'llms'

Content fixes:

• Fixed typo 'informat' in workflows.mdx
• Converted passive voice to active voice in multiple files (feedback.mdx, markdown-export.mdx, adding-sdk-examples.mdx, multiple-responses.mdx, use-cases.mdx)
• Fixed sentence-style capitalization in headings (expandables.mdx, monorepo.mdx, quickstart.mdx, contact-support.mdx, feedback.mdx, openapi-setup.mdx)
• Changed 'file path' to 'path' per style guide (openapi-setup.mdx)
• Fixed 'Autogenerate' to 'Autogenerated' (openapi-setup.mdx)
• Fixed 'Strikethrough' capitalization in text.mdx

Not fixed (requires human review)

The following warnings were not addressed because they may require judgment or could change meaning:

• changelog.mdx (89 warnings): Most are sentence-style capitalization in product release headings (e.g., "Web Editor 3.0", "AI Translations in beta"). These appear intentional as product names.
• First-person pronouns: Some uses in guides (geo.mdx, support-center.mdx, knowledge-base.mdx) may be intentional for conversational tone
• Semicolon usage: Some semicolons in code examples and technical content may be intentional
• "above/below" references: Some spatial references in component docs may be clearer than "preceding/following"

Note

Low Risk
Low risk: changes are limited to Vale lint configuration updates and small copy/heading tweaks in MDX docs, with no runtime or behavioral code changes.

Overview
Resolves Vale CI style warnings by expanding .vale acronym exceptions (e.g., REST, TLS, RBAC, UTC) and adding/adjusting accepted vocabulary terms (including case-insensitive LLMs?).

Applies small doc copy edits across several MDX pages to match style guidance (active-voice rewrites, sentence-case heading/title normalization, and a few terminology/capitalization tweaks such as file path → path and Strikethrough casing).
