Comment:
Are we sure that we actually ''want'' to do this? We have no control over
those external packages. What if somebody has `magma` but with a version
that is not fully compatible with Sage? With Sage's optional packages,
that issue does not occur since we have full control over those packages.
A few comments on the code:
1. Never use `except:`. Use `except Exception:` or some other specific
exception class.
2. Code structure: can we please move all this detect-optional-packages
code to a separate function?
3. Performance: how much time does it take to run all those tests? Note
that #13540 has a system for "lazy" checking of optional dependencies: the
check for a given package is only done if we are actually running a test
involving that package.
