az batch account | 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 should to be escaped so that GitHub does not treat them like live URLs.

### List of Core links that need escaped:
|File name | Build error |
|-|-|
| latest/docs-ref-autogen/batch/account.yml | Link 'https://docs.microsoft.com/azure/batch/batch-virtual-network.""' points to a learn site page that doesn't exist. Check the path or URL and update the link. |
| latest/docs-ref-autogen/batch/account.yml | Link 'https://mykeyvault.vault.azure.net/keys/testkey/6e34a81fef704045975661e297a4c053' points to a page that doesn't exist. Check the path or URL and update the link. |
