feat: add multi-arch images amd64 and arm64

[Gearheads]

What this PR does / why we need it:
This PR add steps for creating images per architecture per Dockerfile, and then grouping those images with docker manifest to create multi-architecture Docker images.

Also, changes the GITHUB_TOKEN for titlechecktitlecheck in an attempt to resolve the issue Error: Resource not accessible by integration.
For reference: aslafy-z/conventional-pr-title-action#119

Edit: I reverted this change, because it did not solve the issue. Instead, there was another error: Error: Bad credentials.

Which issue(s) this PR fixes (optional, in fixes #<issue number>(, fixes #<issue_number>, ...) format, will close the issue(s) when PR gets merged):
Fixes #374, fixes #387

Turns out we cannot merge this until these dependencies have been updated:

• https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/
  • I think this PR will resolve the aws-iam-authenticator issue: [1/2] Release 0.5.4 kubernetes-sigs/aws-iam-authenticator#425
• https://github.com/Azure/kubelogin/releases/

Also, there is a make instruction for testing the release locally:

make release-local

https://github.com/fidelity/kconnect/blob/main/docs/book/src/release.md

EDIT: Looks like aws-iam-authenticator created a new release that supports ARM64: https://github.com/kubernetes-sigs/aws-iam-authenticator/releases/tag/v0.5.5
