docs(builder): add README documentation

[jcbsfilho]

This pull request introduces a patch release for @aziontech/builder focused on improving documentation and package configuration. The most significant change is the addition of a comprehensive README.md to guide users in installing and using the builder utilities for Azion's platform. There are also minor adjustments to package metadata and workflow comments for clarity.

Documentation improvements:

• Added a detailed README.md to packages/builder, covering installation, usage examples with esbuild and webpack, feature descriptions, polyfill usage, API reference, and contribution guidelines.
• Updated the files array in packages/builder/package.json to include the new README.md in published files.

Release and workflow adjustments:

• Added a patch changelog entry for @aziontech/builder noting the new README. (.changeset/huge-sheep-flash.md)
• Commented out the NODE_AUTH_TOKEN line in .github/workflows/release.yml to clarify that it's only needed when publishing a new package.

Other package metadata:

• Marked @aziontech/client as private in its package.json to prevent accidental publishing.
