build: rewrite generate script to use cli-supported codemod configs

[ctran88]

What's New?

• uses a config file instead of cli options due to the extended config file features (slightly better name normalizer and overlay)
• uses the OpenAPI overlay specification to update struct names and codegen modifications for Go instead of jq
  • hoping this is easier to comprehend and maintain over time by others

Screenshots (if appropriate):
