[Key Vault] Update overview page with new library, default branch name

[mccoyp]

Resolves Azure/azure-sdk-for-python#25778. Until now, azure-keyvault-administration has been missing from the overview page for Key Vault. Also, links to the GitHub pages of each package have been using the old name (master) instead of main.

GitHub automatically switched line endings to be consistent throughout the file, which is why the proposed changes seem more significant than they are.
