CENG-581: Allow pointing to Major version to pull latest

[BartoszBlizniak]

This pull request updates the release workflow and improves documentation and output handling for authentication.

Release Workflow Improvements

• The .github/workflows/release.yml workflow was refactored to validate tag formats, use a more precise tag pattern, create releases with improved release notes, and force-update the floating major tag for better version management.

Documentation Updates

• All usage examples in the README.md were updated to reference the stable cloudsmith-io/cloudsmith-cli-action@v1 instead of @master, ensuring best practices and reliability for users. (Addressing Request: Create a tag with just major version #5)

Authentication Output Enhancement

• The src/oidc-auth.js script now sets the OIDC token as an output variable (oidc-token). (Addressing Output oidc-token is not set #6)

Developer experience enhancements:

• Added Husky as a development dependency in package.json and configured a prepare script to install it automatically. [1] [2]
• Introduced a Husky pre-commit hook (.husky/pre-commit) that auto-installs dependencies if missing, builds the action, and stages dist/index.js only if changed, aborting the commit if the build fails. This keeps the bundled output reliably in sync with source changes.

• Updated all README examples from @master to @v1 for better version stability
• Added OIDC token as an action output for programmatic access
