[BUG] typescript-axios not handling response headers

[DavidBiesack]

Description

tool either throws an error about response parameters (5.4.0), or silently ignores them (6.0.0)

openapi-generator version

5.4.0 emits an error
6.0.0 does not show an error, but there is no code to handle the Retry-After response header or constrain its type (to string)

OpenAPI declaration file content or url

openapi: 3.0.0

Generation Details

openapi-generator-cli generate -g typescript-axios -i openapi.yaml -o sdk

Steps to reproduce

above command

for 5.4.0 I get

[main] ERROR o.o.codegen.DefaultCodegen - Not handling class Parameter {
    name: Retry-After
    in: header
    description: null
    required: null
    deprecated: null
    allowEmptyValue: null
    style: null
    explode: null
    allowReserved: null
    schema: null
    examples: null
    example: null
    content: null
    $ref: null
} as Body Parameter at the moment

for 6.0.0 the tool does not emit this ERROR but the emitted code does not support that response header.
