Issue in request section with postman request always being set to content type x-www-form-urlencoded

Describe the bug

The issue I am seeing is we have a request which allows you to specify Content-Type between x-www-form-urlencoded and multipart/form-data shown below. What I am seeing is that even if I have the content type set to multipart/form-data and attach the csv file is that in the postmanRequest it is setting the content type to x-www-form-urlencoded and does not seem to be attaching the file when the call is made. the ApiExplorer function seems to be getting the item and having it defaulted to x-www-form-urlencoded even though the content type in the dropdown defaults to multipart/form-data even manually selecting from the dropdown does not seem to change the content type.

Expected behavior

I would expect the content-type drop down to change the content type for the postmanRequest and attach the file when making the api call.

Current behavior

The content type seems to only be set to x-www-form-urlencoded and does not attach the file when making the api call.

Context

Your Environment

• Version used: we are currently using version 0.0.0-949 with Docusaurus 3.6.3
• Environment name and version (e.g. Chrome 59, node.js 5.4, python 3.7.3):
• Operating System and version (desktop or mobile):
• Link to your project: https://github.com/sailpoint-oss/developer.sailpoint.com

Start by tracing the ApiExplorer function and how it builds postmanRequest, then reproduce the request using multipart/form-data with an attached CSV file. Confirm that manually selecting the content type changes the generated request and that the file is included when the API call is made.
