Create warnings for when the Marqo version is the same as a GitHub release

[pandu-k]

Problem:
We often forget to increment the Marqo's in-code version number. This results in the root endpoint returning a version not representative of the actual version.

Proposed solution:

1. Check if the given version number is in the list of GitHub release tags:

curl https://api.github.com/repos/marqo-ai/marqo/tags

3. Echo warnings that can be parsed by Github:
