Supports resolution of

• Migrate CircleCI to supported Node.js version #1145
• Migrate to current Docker version #1095

Issue

• Docker Buildx v0.10.0 introduced a breaking change causing multi-architecture manifests to use oci instead of docker imageType formats. The release notes warn about issues with registry and runtime support. This already caused a issue in this repo (see docker-image-not-found not compatible with oci mediatype #1141). It is unknown whether allowing the manifest imageType to change for Cypress Docker images would cause usage issues in users' environments and it would have to be considered as a breaking change for Cypress Docker.

• This repo is currently using Buildx v0.9.1 so this issue needs to be considered and prepared before any update to Buildx v0.10.x takes place:

  Image tag	Node.js	Docker Engine	buildx	Status
  ubuntu-2204:2022.10.2	16.17.1	20.10.18	v0.9.1	Current

Change

In order to keep the current manifest schema as follows:

"schemaVersion": 2,
"mediaType": "application/vnd.docker.distribution.manifest.list.v2+json",

instead of moving to

"schemaVersion": 2,
"mediaType": "application/vnd.oci.image.index.v1+json",

an environment variable setting BUILDX_NO_DEFAULT_ATTESTATIONS=1, introduced in Buildx 0.10.4, is added to the push job of the circle.yml workflow.
