Fix Windows CI: update swift-docc-plugin to 1.4.6

[leogdion]

Summary

• Updates swift-docc-plugin from 1.4.5 → 1.4.6 in Package.resolved

Problem

Windows CI (windows-2022 and windows-2025) was failing with:

error: cannot find 'Lock' in scope
error: cannot find type 'SnippetExtractor' in scope
error: cannot find type 'ParsedSymbolGraphArguments' in scope

The root cause: swift-docc-plugin uses a Symbolic Links/ directory to share source files across plugin targets. On Windows, without proper .gitattributes, git checks these symlinks out as plain text files (containing just the path string). The Swift compiler then tries to compile these empty stubs, producing missing-type errors.

Fix

swift-docc-plugin 1.4.6 release notes: "Add .gitattributes for symlinks on Windows." — this ensures git resolves symlinks to real source files on Windows checkouts.

Package.swift already declares from: "1.4.0", so only Package.resolved needed updating.

Test plan

• Build on Windows (windows-2022) passes
• Build on Windows (windows-2025) passes

Code Review: Fix Windows CI - update swift-docc-plugin to 1.4.6

The Package.resolved update is the right fix — swift-docc-plugin 1.4.6 adds .gitattributes for symlink handling on Windows, which directly addresses the missing-type errors from symlinks being checked out as text files.

Duplicate PR notice

This PR (131) and PR 132 are both from the same branch 'fix/windows-docc-plugin-symlinks' but target different bases:

• PR 131 targets '128-workflow-updates'
• PR 132 targets 'v0.0.4'

One of them should be closed to avoid confusion. If the workflow optimizations from 128-workflow-updates are meant to land first, PR 131 (on top of that branch) is the right one to keep. If this fix needs to go into the release branch independently, PR 132 is correct — but then PR 131 becomes redundant once 129 merges.

The fix itself

Minimal and correct. Package.swift already declares 'from: "1.4.0"' so only Package.resolved needed updating. No source changes required.
