fix: bot app error handling in template and SDK

[qinezh]

Update bot templates and SDK to send a message on error only when the activity is a message directed to it.

This PR covers:

• Update the error handling part in ConversationBot of TeamsFx SDK
• Update the error handling part in Bot app JS/TS template if TeamsFx SDK is not used.
• Update the SDK version in Bot app JS/TS template if Teams SDK is used.

The updates to .NET version of TeamsFx SDK and bot template will be covered in another separated PR, as it's not related to the 5.6.0 release.
