docs: update installation instructions

[lucaseck]

What was the problem/requirement? (What/Why)

The GitHub installation docs for the submitter were not clear if the submitter installer was being used vs a manual installation.

104

What was the solution? (How)

• Created a new section in the README for getting started with the submitter
• Linked from the README to the DEVELOPMENT file for manual instructions needed after running the submitter installer. In a future PR I'll likely remove the instructions entirely from the DEVELOPMENT.md file and have the ones for the submitter installer manual steps point to the AWS docs
• Linked from the README to the DEVELOPMENT file if doing a manual installation

  What is the impact of this change?

  Clearer instructions for installation from either using the submitter installer or a manual installation

  How was this change tested?

  N/A

  Was this change documented?

  It is a docs change

  Is this a breaking change?

  No
