Fix formatting issues in docs/index.md

[jfcantu]

Description

Removed a couple duplicate lines from docs/index.md that was causing the code formatting in "Example Usage" to terminate prematurely in some renderings (e.g: https://registry.terraform.io/providers/hashicorp/ad/latest/docs )

Good catch. The docs are generated by running https://github.com/hashicorp/terraform-plugin-docs so I went ahead and updated the original template too.

Thanks!
