Cardinality fails in small special linear groups

[jukkakohonen]

Steps To Reproduce

Using SageMath version 10.3.beta1, Release Date: 2023-12-10, run:

sage: SL(1, QQ).cardinality()

Expected Behavior

Mathematically I would expect it to be 1, in fact for any special linear group of degree 1 regardless of the field, because the only $1 \times 1$ matrix with determinant one is $[1]$, where $1$ is the multiplicative unity.

If not implemented, at least it should raise a NotImplementedError.

Actual Behavior

It goes into an infinite recursion.

sage: SL(1, QQ).cardinality()
...
RecursionError: maximum recursion depth exceeded

Additional Information

Same happens with SL(1,RR), and also with is_finite.

Environment

- **OS**: Ubuntu 20.04.5 LTS
- **Sage Version**: SageMath version 10.3.beta1, Release Date: 2023-12-10

Also happens on SageMath version 9.0, Release Date: 2020-01-01, with a slightly different error message `RecursionError: maximum recursion depth exceeded while calling a Python object`.
