fix: handle trailing commas in tree-sitter-swift binding.gyp patch

Browse source 
The patch script fails to parse tree-sitter-swift@0.6.0's binding.gyp
because the file contains both Python-style # comments AND trailing
commas in JSON arrays. The existing regex strips # comments but leaves
trailing commas, causing JSON.parse() to fail with:

  "Unexpected token ']'"

This silently prevents tree-sitter-swift from building, which means
Swift files are skipped entirely during analysis.

Fix: add a second regex pass to strip trailing commas before ] or }
after comment removal.

Fixes #386, #406
