Geometry container versioning #2289
Description
Right now the Geometry containers (https://ghcr.io/ansys/geometry) are not tagged differently when new builds come out, it is just the same rolling tags core-linux-26.1 and core-linux-latest (using Linux as an example), with no easy way to reference previous builds.
This makes it unnecessarily difficult for users to test and evaluate the images when newer builds come out. Untagged images are also being deleted (which is understandable and a good idea in isolation, but makes this problem even worse).
As an alternative, see what the Fluent team is doing: https://ghcr.io/ansys/fluent, each image is tagged with the Fluent build ID (the same one used in the desktop application as well), so it makes it much easier to evaluate new builds, stick to using older builds if needed for a specific client, and also report issues when they do occur.
Geometry could do versioning like core-linux-26.1.X for the containers, where X corresponds to some build ID that you already use, if applicable
