Change allowed incoterms

[clalexander]

fix: change allowed incoterms

Changed Allowed incoterms to allowed_incoterms in openapi.yaml, openapi.json and docs/index.html to match with existing schema patterns and allow openapi generators to build without Typescript errors.

npx openapi-generator-cli generate -i openapi.yaml -g typescript-fetch -o ./src # does not validate

npx openapi-generator-cli generate -i openapi.yaml -g typescript-fetch --skip-validate -o ./src # does generates typescript errors
