fix: show numbers in educational abacus examples

Changed showNumbers from "never" to "always" for all educational abacus
examples in the guide and live preview. This ensures that users can see
the numerical values below each abacus, which is essential for learning
how to read soroban numbers.

Educational examples should always show numbers to help users understand
the relationship between bead positions and their numerical values.
