Remove nanoTDF documentation

[strantalis]

Remove all nanoTDF references from public documentation and code samples as the feature is being made proprietary.

Changes

• Removed KAS NanoTDF rewrap section and diagram from Key Access documentation
• Deleted NanoTDF code samples (Java collection examples, TDF encryption example)
• Removed NanoTDF feature matrix entries and constraints in base key documentation
• Updated OpenAPI spec descriptions to remove nanoTDF-specific language
• Updated build configuration to stop generating nanoTDF specification pages

Note

OpenAPI specs in /specs are vendored from upstream. Local modifications will be overwritten when running npm run update-vendored-yaml. The upstream opentdf/platform repository should be updated separately.

Summary of Changes

Hello @strantalis, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a significant cleanup effort by removing all public-facing documentation and code samples pertaining to the nanoTDF feature. This change reflects the feature's new proprietary status, ensuring that the public documentation accurately represents the available open-source offerings. The updates span across various documentation files, code examples, OpenAPI specifications, and build configurations to eliminate any mention or generation of nanoTDF-related content.

Highlights

• NanoTDF Documentation Removal: All public documentation and code samples related to nanoTDF have been removed, aligning with the feature's transition to proprietary status.
• OpenAPI Specification Updates: Descriptions within various OpenAPI specifications have been generalized to remove explicit nanoTDF references, replacing them with broader terms like "EC-based wrapping" or "formats that embed it."
• Build Configuration Streamlining: The build process has been updated to cease generating nanoTDF-specific documentation pages, ensuring a cleaner public documentation site.

Code Review

This pull request effectively removes most references to nanoTDF from the documentation, code samples, and build configurations, aligning with the goal of making the feature proprietary. The changes are generally well-executed. However, I've identified a critical issue in one of the Java code samples where a typo was introduced. Additionally, this particular code sample file, being a nanoTDF example, seems to have been overlooked for deletion as per the PR's objective. Please see the specific comment for details.
