[typescript-axios] query property renamed to _query

Description

We use swagger-codegen and have a property query, but in the Typescript export it is renamed to _query. With previous versions it worked.

Swagger-codegen version

3.0.55, seems to be a regression

Command line used for generation

swagger-codegen generate -i schema.yaml -l typescript-axios -o out

Steps to reproduce

1. Run swagger-codegen
2. inspect result, _query? should be query?:

Suggest a fix/enhancement

Start by running the documented swagger-codegen command with the provided OpenAPI schema.yaml and inspect the generated TypeScript output. Trace the typescript-axios generation path to determine why the BasicEvent property becomes _query; done means the generated interface preserves the property name query.
