Add a url to check version

[vishalchangrani]

Is your feature request related to a problem? Please describe.
Currently, there is no way to check what version of the code base has been deployed to production and staging leading to a lot of confusion.

Describe the solution you'd like
A link on the UI which provides the front end and the backend version.
e.g. https://cast.fyi/version#/ which provides the SHA of the commit for the frontend and the backend code.

Additional context

@vishalchangrani The Frontend and Backend files are in same parent repository so they have same commit message.
We can render the SHA for the entire application.

But that would not guarantee that the FE and BE are indeed running with that deployed version.
Could the tag be part of the release process?

@vishalchangrani I'm not sure how tags are being used for prod/staging, maybe we can have a discussion in our today's syncup.
