Missing documentation on BotService connections

**Bicep version**
0.11.1

**Describe the bug**
Trying to add a Generic OAuth 2 connection via Bicep but there's nothing to show what the value should be for the serviceProviderId.

**To Reproduce**
There's no example of the properties for each connection similar to how there are examples for the Channels. https://learn.microsoft.com/en-us/azure/templates/microsoft.botservice/2022-09-15/botservices/connections?pivots=deployment-language-bicep#connectionsettingparameter

Start with the linked Microsoft Learn Bot Services connections page and its connectionSettingParameter section, comparing the existing Channels examples. Document the properties for each connection type, including the expected serviceProviderId for a Generic OAuth 2 connection. Done means the page shows usable examples for the connection properties requested in the issue.
