az bot | example links need to be escaped in reference content

### Describe the bug

Please escape these example links in source code so they are corrected in MicrosoftDocs/azure-docs-cli autogenerated reference content.

Example links are needed in reference examples, but they need to be escaped so that GitHub does not treat them like live URLs.

### List of links that need escaped:
|File name | Build error |
|-|-|
| latest/docs-ref-autogen/bot/directline.yml | Link 'https://mybotsite1.azurewebsites.net' points to a page that doesn't exist. Check the path or URL and update the link. |
| latest/docs-ref-autogen/bot/directline.yml | Link 'https://mybotsite2.azurewebsites.net' points to a page that doesn't exist. Check the path or URL and update the link. |
