Limit bloom_3d float output to two decimal places. (#20897)

Objective
Improve the readability of the float output in the bloom_3d example by
formatting it to two decimal places.
This makes the output cleaner and more consistent.

Solution
Used Rust’s formatting syntax (e.g., {:.2}) to ensure floats are
displayed with exactly two decimal places.
Applied this to all relevant print or debug output lines in the bloom_3d
example.
