Deprecate old Dev docs

[Souheil-Yazji]

We still have https://statcan.github.io/aaw-developer-docs/ and https://statcan.github.io/aaw/dev

Let's part with the first one and continue maintaining the /aw/dev location moving forward.

To Do

• [x] Consolidate between the two doc pages
• [x] Archive the aaw-developer-docs repo
• [x] https://confluenceb.statcan.ca/display/DAaaS/Kubernetes+documentation does not seem to be in the new documentation
• [x] https://statcan.github.io/aaw/dev/ The getting started link is broken

• The old documentation is entirely contained in the new documentation.
• I fixed the broken link.
• I'll need repo admin rights to archive the aaw-developer-docs repo.

I think for the confluence link, it contains the details to set-up/onboard new developers and that's what we'd like to have in the Dev docs.

I actually made https://gist.github.com/Souheil-Yazji/4720d86a763068263585bd562c21c88c to help with a quick setup, we could possibly just attach the kubectl config and AZcli setup there as well.

I added info from the confluence page and the gist above.
