docs: fix verbose-bit-mask example (#14055)
changelog: none
`x & 15 == 0` is not equivalent to `x.trailing_zeros() > 4`, as `x =
0b10000` is true for the former and false for the latter.
In fact, clippy itself suggests the following:
```rust
pub fn src(x: i32) -> bool {
x & 15 == 0 // ~error: bit mask could be simplified with a call to `trailing_zeros`
^^^^^^^^^^^ help: try: `x.trailing_zeros() >= 4`
}
```
