fix(sdks): improve typescript-language-server PnP auto import support

[amyanger]

Summary

This PR fixes inconsistent auto import behavior when using typescript-language-server with PnP environments (Fixes #6845).

Problem

The issue reported that auto imports work inconsistently in PnP environments when using typescript-language-server with Neovim. Some imports like PutObjectCommand work correctly, while others like AaaaRecord fail to auto-import despite being suggested.

Root Cause

1. Missing VSCode SDK Integration: typescript-language-server had null configuration in the VSCode SDK, unlike the regular typescript package
2. Lack of PnP Path Resolution: typescript-language-server wasn't receiving the same TypeScript server monkey patches that handle PnP virtual path resolution and auto imports

Solution

• Added VSCode integration wrapper for typescript-language-server with proper TypeScript SDK configuration
• Applied TypeScript server monkey patches to typescript-language-server base wrapper, including:
  • PnP virtual path resolution
  • Editor path normalization (VSCode, Neovim, etc.)
  • Plugin loading fixes
  • Auto import path handling

Changes

• packages/yarnpkg-sdks/sources/sdks/vscode.ts: Added generateTypescriptLanguageServerWrapper and updated SDK configuration
• packages/yarnpkg-sdks/sources/sdks/base.ts: Enhanced base wrapper with comprehensive TypeScript server monkey patches

Testing

• ✅ All unit tests pass (yarn test:unit)
• ✅ Code passes linting (yarn test:lint)
• ✅ Constraints check passes (yarn constraints)
• ✅ Package builds successfully

Package Version

The @yarnpkg/sdks package has been modified and will need a version bump as detected by yarn version check.
