Record final demo for a user of BenchPress

[msha1026]

I would like to record a demo that will be targeted towards users of BenchPress in order to demo the current state of the PowerShell module and how they can use it for their testing needs. This issue is dependent on #283, #245, and #285 completion.

Upload to Benchpress teams channel for now

• Demo recorded showing the following:
  • How to install from PSGallery
  • How to use the module (using the Canonical app as the example)
  • Any documentation that may be useful for users
