Pull request overview

Updates the project README to reflect current GAP Docker image tags and to document what’s included in each image variant so users can choose the right one.

Changes:

• Bumped referenced image tags in the Mermaid diagram and usage examples to newer GAP versions.
• Added descriptions for bare, slim, full, jupyter-gap, and buildfull (with an Ubuntu 22.04 LTS footnote).
• Expanded the README structure with a clearer “Usage” section.

README.md:55

• This docker run example is a duplicate of the preceding 4.14.0-bare command. It looks like one of these blocks was meant to demonstrate a different tag (e.g., slim) or a different version; please remove the duplicate or replace it with the intended example, and consider adding a short note explaining why the examples use different versions (4.15.1, 4.15.0, 4.14.0).

docker run -it ghcr.io/gap-system/gap:4.14.0-bare

README.md:55

• The Usage section currently repeats the exact same docker run ...:4.14.0-bare example twice, which looks accidental and may confuse readers. Consider removing the duplicate block or replacing it with an example for a different tag/variant (e.g., slim or jupyter-gap).

docker run -it ghcr.io/gap-system/gap:4.14.0-bare

docker run -it ghcr.io/gap-system/gap:4.14.0-bare
