Repo release:

• [x] Last PR is to push the version number of metviewer image from dockerhub in docker-compose.yml files (v4.1.0). Made this edit locally, then created tag and pushed that tag to the repo. This way, the main branch retains used of "latest" metviewer image, but release v4.1.0 will be hard coded to that version, which I think is what we want.
• [x] Create release tag 4.1.0 (This will automatically build new 4.1.0 images on dockerhub)
• [x] Confirm Dockerhub builds for this tag

Create AMIs:

• [x] Base env
• [x] Fully loaded

Website/Tutorial Updates:

• [x] Update version numbers (Tutorial)
• [x] Add docker pull singularity instructions for metviewer under Software Containers of Tutorial
• [x] Don't forget to update version in build AMI instructions (buried deep!)
• [x] Sanity check testing of online tutorial and docker pull dockerhub images
• [x] Create GH Release page
• [x] Update Downloads page and release versions
