[BUG] Manage Connections Documentation Uses Outdated api_version

[CraigCallender]

Describe the bug
Following the documentation here and scrolling to the bottom. It would appear that one could add the auth_mode YAML field with a value of meid. What isn't noted is that a value of meid for auth_mode isn't supported until api_version: "2024-02-15-preview". The fact that higher up in this document the example file shows an api_version: "2023-03-15-preview" makes implementing MEID authentication via following this document impossible.

How To Reproduce the bug
Steps to reproduce the behavior, how frequent can you experience the bug:

1. Follow the documentation and attempt to create a connection via MEID auth. You'll get an unauthorized.

Expected behavior
A promptflow connection is created using MEID as auth.
