`manual_is_multiple_of` suggests change that could alter behaviour

[ojeda]

Description

a % b == 0 is not equivalent to a.is_multiple_of(b): b == 0 panics in the former, while it may return false or true in the latter.

However, the Clippy lint manual_is_multiple_of does not mention this potential change in behavior -- the user may or may not want the non-panicking behavior.

Therefore, should manual_is_multiple_of mention that the replacement may change behavior in b == 0 cases?

(This is very similar to #14333 about manual_div_ceil, but for manual_is_multiple_of.)
