fix: broken accept header

[OmarAlJarrah]

Situation

The current implementation of the operation_params.mustache template in the expediagroup-sdk uses the httpAcceptHeader block to append the "Accept" header with the media types. However, this approach does not handle multiple media types effectively, prompting the need for a more flexible solution.

Task

The goal is to refactor the operation_params.mustache template to allow appending multiple media types to the "Accept" header. This change aims to improve the handling of media types in the generated SDK code.

Action

The changes made include:

• Replacing the httpAcceptHeader block with the allowedMediaTypes block.
• Iterating over the mediaTypes within the allowedMediaTypes block.
• Appending each media type individually to the "Accept" header using the append("Accept", "{{.}}") statement.
