docs: add Deno to installation instructions

[bartlomieju]

🎯 Changes

👋 Bartek from the Deno team here. This adds a Deno install command to the React Query installation docs (docs/framework/react/installation.md), alongside the existing npm / pnpm / yarn / bun blocks. Since Deno is a drop-in replacement for npm these days, deno add @tanstack/react-query works as a drop-in.

✅ Checklist

• I have followed the steps in the Contributing guide.
• I have tested this code locally with pnpm run test:pr (N/A — docs-only content change)

🚀 Release Impact

• This change is docs/CI/dev-only (no release).

Disclosure: I work on Deno, so I have an interest here. The goal is parity with the package managers you already list, not promotion. This PR was prepared with AI assistance under human supervision: I review every change myself and personally respond to any comments or review feedback.
