Added Installer

[IvanMurzak]

This pull request introduces a comprehensive set of GitHub Actions workflows for automating release, testing, and artifact management for the Unity Gyroscope Parallax project. It adds robust CI/CD pipelines for both pull requests and releases, supporting multiple Unity versions and platforms, and ensures that only validated code is published. Additionally, it removes the package README file and makes a minor adjustment to .gitignore.

Continuous Integration & Release Automation

• Added a full-featured release workflow in .github/workflows/release.yml that builds, tests, and publishes Unity installer packages, generates release notes, tags releases, and cleans up artifacts. It runs tests across multiple Unity versions and modes before publishing.
• Introduced a pull request testing workflow in .github/workflows/test_pull_request.yml that runs tests on all supported Unity versions and modes for PRs to main and dev, ensuring code quality before merging.
• Added a reusable workflow in .github/workflows/test_unity_plugin.yml for running Unity tests on both Windows and Ubuntu, with safeguards against running secrets on unsafe PRs and support for matrix builds.

Documentation and Project Structure

• Removed the package documentation file Assets/_PackageRoot/README.md, which previously described features, usage, and installation instructions for the Unity Gyroscope Parallax package.

Miscellaneous

• Removed an exception rule from Assets/_PackageRoot/Scripts/.gitignore that previously ensured .gitignore itself was tracked.
