Add minimum version of conda gap package

[tobiasdiez]

📚 Description

Since #35093, sage no longer builds with gap 4.11. With this PR the new minimum version is correctly specified for the conda installation. This currently doesn't work as there is no suitable conda package yet, see conda-forge/gap-feedstock#68. However, better fail with a good error message then some random warning during build.

It would be nice if in the future breaking package updates would only happen if conda provides a suitable package.
