Consolidate scanners

[LilaKelland]

• Consolidated the scanners.

• Changed dev environment to node 18 (may need to change this to alpine, and in the Dockerfile rather than json)

Removed:

• service discovery
• endpoint dispatcher
• github octokit repo details, (and the corresponding superfluous functions format the response)

Now:

• Moved to receive payload from webhook (github-clone-repo and github-octokit-check both subscribe to GitHubEvents) rather than endpoint-dispatcher
• github-clone-repo still clones repo
• github-checks-on-cloned repo scans the cloned repo for files and directories (note - feeling like once we have more thorugh scans for api and tests, we'll eliminate those here (ie dependabot.yaml)
• github-octokit-checks calls to the octokit API to retrieve repo metadata details and information on security protocols implemented.
• There are couple of checks in github-octokit-checks that require main branch (which can be pulled from githubrepodetails) so either that can be linked, or can be published to a branch check (that this service is subscribed to as well) and be handled that way. Right now blanket passing main branch to all calls, but will need to update this in the future.

Still to do

• move tests over and create more for better coverage
• save to db
