Add patch for rescript-json-combinators to generate .bs.js files

The @glennsl/rescript-json-combinators package ships without compiled
.bs.js files and its bsconfig.json lacks package-specs configuration.
This causes module resolution failures when Rspack tries to import
these files.

Add patch-package to apply a fix that:
- Removes reference to non-existent examples directory
- Adds package-specs for ES module output
- Configures .bs.js suffix for compiled files

This ensures yarn res:build compiles the dependency correctly.
