OAuth2 client credentials are sent with wrong Content-Type

[nverbos-godaddy]

Description

When an OAuth2 access token is requested from an OAuth2 Authorization server's token endpoint, the credentials are sent using the application/json Content-Type, but client credentials should be sent using the application/x-www-form-urlencoded according to the OAuth 2.0 RFC

Version of SDK

v0.3.1

Reproduction

1. Configure the openfga client using the OAuth2 Credentials example in the README
2. Observe that the content-type is set to application/json

Expected behavior

When an OAuth2 token is requested from an OAuth2 Authorization server, the credentials are sent using the application/x-www-form-urlencoded content-type as specified in the OAuth 2.0 RFC

@le-yams just looping you in as you had contributed that code. Would changing the content type still work for you?

Absolutely, @nverbos-godaddy is right 😄

@rhamzeh I've created a PR in the sdk-generator project to fix this.
