New: Basic Cache Provider

A new MIT-licensed Basic Caching provider is now available as an alternative to the proprietary Enhanced Caching provided by gradle-actions-caching. Choose Basic Caching by setting cache-provider: basic on setup-gradle or dependency-submission actions.

• Built on @actions/cache -- fully open source
• Caches ~/.gradle/caches and ~/.gradle/wrapper directories
• Cache key derived from build files (*.gradle*, gradle-wrapper.properties, etc.)
• Clean cache on build file changes (no restore keys, preventing stale entry accumulation)

Limitations vs Enhanced Caching: No cache cleanup, no deduplication of cached content, cached content is fixed unless build files change.

Revamped Licensing & Distribution Documentation

• New DISTRIBUTION.md documents the licensing of each component (particularly Basic Caching vs Enhanced Caching)
• Simplified licensing notices in README, docs, and runtime log output
• Clear usage tiers: Enhanced Caching is free for public repos and in Free Preview for private repos

What's Changed

• Use a unique cache entry for wrapper-validation test by @​bigdaz in #​921
• Update Dependencies by @​bigdaz in #​922
• Update dependencies and resolve npm vulnerabilities by @​bigdaz in #​933
