fix(typescript-nestjs): handle query params serialization properly

[mahmoudzeyada]

Fix: Properly Serialize Query Parameters in OpenAPI Generator for TypeScript NestJS

Issue

The current template assigns query parameters using:

queryParameters['{{baseName}}'] = {{paramName}}.join(COLLECTION_FORMATS['{{collectionFormat}}']);

However, this does not work with URLSearchParams, as it does not allow direct property assignment. Instead, it requires .set() or .append() to properly modify query parameters.

Fix

Replace the assignment with:

queryParameters.append('{{baseName}}', {{paramName}}.join(COLLECTION_FORMATS['{{collectionFormat}}']));

This ensures that query parameters are correctly added and serialized in the request URL.
