bump up directline

Ref: microsoft/BotFramework-DirectLineJS#443

Changelog Entry

• Bumped botframework-directlinejs to include support for the new streaming property, by @pranavjoshi001, in PR #5686

Description

Bumps botframework-directlinejs to include support for the new streaming property. This enables Web Chat to pass the streaming configuration when creating a DirectLine connection.

Design

• When streaming: true - deliveryMode = "stream" will be passed in post request, If the server supports streaming, responses will be delivered as stitched streams
• When streaming: false or omitted - Current behavior is preserved, no changes to existing flow

This change is fully backward compatible.

Specific Changes

• Bumped botframework-directlinejs dependency version to include streaming property support

• I have added tests and executed them locally
• I have updated CHANGELOG.md
• I have updated documentation
