fix(sorts): remove shadowed type parameter from bogo_sort is_sorted helper

In PEP 695 syntax, T is already bound by the outer function bogo_sort[T: Comparable]. Re-declaring [T: Comparable] on the nested is_sorted helper shadows T and causes ty check to emit error[shadowed-type-variable].

Remove [T: Comparable] from is_sorted so it uses the enclosing type variable T, matching other sorting algorithms in sorts/ (e.g. circle_sort, merge_sort).

Validation:
- uvx ty check sorts/bogo_sort.py -> All checks passed
- uvx pytest sorts/bogo_sort.py --doctest-modules -> 1 passed
- uvx pytest tests/test_sorts.py -k test_bogo_sort -> 1 passed
- uvx ruff check / format -> clean
