replace deprecated 'typings' field with standard 'types' in package.json

[kaizencode-art]

Description

Replaces deprecated "typings" field with "types" in package.json.

Without this fix, some IDEs (e.g., VS Code) fail to resolve type definitions correctly when using this package, due to "typings" being ignored in favor of the standard "types" field.

@wing328 any idea what's the ci issue ?

I can't seem to open the CircleCI page for some reason - what's the message in there?

[wing328]

me neither - i got "page not found"

anyway node 0 tests in circleci is not related to typescript: https://github.com/OpenAPITools/openapi-generator/blob/master/CI/circle_parallel.sh#L116

so it can be ignored for this change
