Summary

Follows on from #33 (the .csproj auto-detection rewrite) with the matching README updates:

• Step 2 now includes DocFxForUnity.csproj in the list of files to copy, with a tip on renaming it and keeping docfx.json in sync.
• Step 9 notes that Unity Hub DLLs are auto-detected — no manual "Open C# Project" step needed.
• "Generate automatically" section also lists the .csproj in the diff block.
• New "Advanced: custom Unity path (UNITY_MANAGED_PATH)" section explains the three-priority resolution order and shows the exact set/export commands for Windows, macOS, and Linux.
• Removed the outdated troubleshooting tip that told users to open Unity and click Asset > Open C# Project to generate a .csproj.
• Added a replacement troubleshooting entry pointing users to the new advanced section when DLLs are not found.

Test plan

• Read through the rendered README on the PR page and verify formatting (tables, diff blocks, code blocks)
• Confirm the UNITY_MANAGED_PATH paths match the globs used in DocFxForUnity.csproj
• Confirm the removed "Open C# Project" tip is gone
