copilot: remove InlineDocIntent and /doc command

[jrieken]

Summary

Remove the InlineDocIntent (/doc slash command) from the Copilot extension entirely - implementation, registration, package.json contribution, localization string, and all dedicated tests.

Session Context

Key decisions from the development session:

• Delete dedicated test files entirely: The slashDoc.*.stest.ts files (cpp, java, rb, ts) were ~95%+ focused on /doc intent testing. The few incidental assertions for other intents (e.g., one Intent.Explain check, one Intent.Tests check) were not robust standalone tests and were dropped rather than extracted.
• Remove doc query objects from multi-query tests: In inlineGenerateCode.stest.ts, the 'add doc' and 'document the functions with jsdoc' query steps within multi-turn test scenarios were removed, keeping the remaining queries intact.
• Remove intent classification tests: Two generateIntentTest calls in inlineChatIntent.stest.ts ('add comment' and 'write jsdoc') that expected InlineDocIntent.ID were removed.

Changes

• Deleted docIntent.tsx - the InlineDocIntent class, DocInvocation, and DocPrompt
• Removed InlineDocIntent from allIntents.ts intent registry
• Removed /doc command contribution from package.json chat participant
• Removed copilot.workspace.doc.description from package.nls.json
• Deleted 4 dedicated test files: slashDoc.{cpp,java,rb,ts}.stest.ts
• Cleaned up doc-related test cases from inlineGenerateCode.stest.ts and inlineChatIntent.stest.ts
• Updated simulation baselines and outcome files

Pull request overview

This PR removes the Copilot extension’s inline documentation intent (InlineDocIntent) and the /doc slash command end-to-end (intent implementation/registration, command contribution + localization, and the dedicated simulation tests/baselines tied to /doc).

Changes:

• Removed the InlineDocIntent implementation and unregistered it from the intent registry.
• Removed the /doc chat command contribution and its localized description string.
• Deleted /doc-focused simulation tests and updated simulation baselines/outcome request manifests accordingly.
