Add a github action for creating a build on every push

[lakshayman]

Creating a build action in GitHub actions on every push will let us know if it will fail in deployment or not,

Shouldn't this be caught in the test?

@prakashchoudhary07 Dependency issues are not caught in the test. I think we can build it before the testing action. The build is created by AWS SAM, for testing we are doing it separately for every golang function.
