fix: restore indicators to jellybean_raindrops (qmk#21792)

After qmk#21169, rgb_matrix_indicators() was limited to running on the
final render iteration. Since the jellybean_raindrops animation
immediately returns false after updating a single LED, the iteration
count no longer ends up high enough to render non-advanced indicators.

This change also brings jellybean_raindrops more in line with raindrops.
