fix: Remove CVE-2022-25881 vulnerability by updating the http-cache-semantics package

[sw-joelmut]

Addresses #4684
#minor

Description

This PR updates the version of the http-cache-semantics package to 4.1.1 to fix the CVE-2022-25881 vulnerability.
Along the way, to address this http-cache-semantics package issue with 3.x version, we removed bf-chatdown package, and ported its code to botbuilder-core as internal testing, to remove unnecessary vulnerable dependencies the project isn't using.
Additionally, the lodash.template https://github.com/microsoft/botbuilder-js/security/dependabot/344 - CVE-2021-23337 was also address.

Specific Changes

• Updated http-cache-semantics to 4.1.1.
• Removed bf-chatdown as it was using http-cache-semantics 3.x version.
• Ported and adapted bf-chatdown code to botbuilder-core for internal testing.
• Fixed transcripts tests to work with latest botbuilder changes.
• Added transcripts tests to the testing flow.
• Fixed lint errors with chatdown and botbuilder-dialogs-adaptive.

Testing

The following image shows the http-cache-semantics updated version, and the trascripts tests passing.
