Previously, the docker images used on CI where specified by a tag (`10.16` and `10.16-browsers`). Since tags are not immutable, this only pins specific characteristics of the environment (e.g. the OS type and the Node.js version), but not others. Especially when using a tag that does not specify the patch version (e.g. `10.16` instead of `10.16.0`), it is inevitable that the image will change at some point, potentially leading to unrelated failures due to changes in the environment. One source of such failures can be the Chrome version used in tests. Since we install a specific ChromeDriver version (that is only compatible with specific Chrome version ranges), unexpectedly updating to a newer Chrome version may break the tests if the new version falls outside the range of supported version for our pinned ChromeDriver. Using a tag that specifies the patch version (e.g. `10.16.0`) or even the OS version (e.g. `10.16.0-buster`) is safer (i.e. has a lower probability of introducing the kind of breakages described above), but is still not fully hermetic. This commit prevents such breakages by pinning the docker images by ID. Image IDs are based on the image's digest (SHA256) and are thus immutable, ensuring that all CI jobs will be running on the exact same image. See [here][1] for more info on pre-built CircleCI docker images and more specifically [pinning images by ID][2].
