fix: improve error handling, templating, and Python config options (#…

…1215)

- Handle 4XX and 5XX error ranges separately to ensure proper response

- Escape template-sensitive characters in examples across all targets to
prevent templating errors in usage snippets.
 - Add `enableCustomCodeRegions` configuration option to Pythonv2 SDK.
