docs: update repository and npm READMEs for 2.0.7

[CedricGuillemet]

Describe the change

Update the repository README and npm package README source for 2.0.7, identifying it as the latest stable release in preparation for publication.

• Add the 2.0.7 installation command, compatibility rows, and Babylon Native source pin f4d9efbeeabcfec24105373b99e54fe147669fc1. Document the native/JsRuntimeHost dependency update and removal of obsolete minz links already implemented on master; Babylon.js and React Native baselines remain unchanged from 2.0.6.
• Preserve historical 2.0.x peer ranges and native source pins. Record resolved Playground versions rather than manifest lower bounds: 2.0.5 locks React Native Windows 0.81.21; 2.0.6 and 2.0.7 use React Native 0.81.6 with React Native Windows 0.81.35. Explain the NuGet-aligned Windows pin and the ^0.81.4 manifest range.
• Refresh Android ABI/ARCore/Kotlin guidance, iOS 16 and CMake configuration, camera permissions, and experimental Windows integration.
• Correct contributor setup, toolchains, Playground launching, packaging, and debugging guidance. Use BRNPlayground.xcworkspace with the Playground scheme for iOS instead of the CLI-selected workspace, and fix the antiAliasing example.

The npm README is copied from Modules/@babylonjs/react-native/README.md during packaging and reaches npm with the next package publication. This PR changes only the two READMEs; it does not change runtime code or package versions.

No linked issue.

Screenshots

N/A — documentation-only changes.

Documentation

Have you updated the documentation to reflect your changes? (Yes or N/A)

Yes — updated README.md and Modules/@babylonjs/react-native/README.md.

Testing

Have you tested the final iteration of your changes? (Yes or N/A or I need help testing on [Android|iOS|Windows])

N/A for Playground testing — documentation-only changes.

• git diff --check origin/master...HEAD — passed.
• node - (read-only README assertions supplied through stdin) — passed: Markdown fences, 14 local links/anchors, latest-version wording, eight Babylon Native source pins and Babylon.js peer ranges, resolved Playground versions for 2.0.5–2.0.7, corrected iOS workspace instructions, and the antiAliasing example. Historical entries were checked against release tags; the 2.0.7 entry was checked against origin/master ahead of release.

Native builds, TypeScript checks, and manual Android/iOS/Windows device testing were not run.
