[`tuple_array_conversions`]: move from `complexity` to `nursery`

The lint suggestion is arguably often less readable and more complex than the original code.

For example, which of the following is the most readable:
```rust
let _vertices = edges.flat_map(|(src, dst)| [src, dst]);
let _vertices = edges.flat_map(<_ as Into<[i32; 2]>>::into);
let _vertices = edges.flat_map(<[i32; 2]>::from);
```

The lint can be useful, but really only applies if the tuple is either long enough that naming the fields is silly (maybe at least 4 entries long), or if the author intends the fields to be homogenous, which is author intent and can't be determined by the lint. Therefore I think the lint should be marked as pedantic.

Currently, there are also a lot of false positives with the lint:

* https://github.com/rust-lang/rust-clippy/issues/11085
* https://github.com/rust-lang/rust-clippy/issues/11100 (https://github.com/rust-lang/rust-clippy/pull/11105)
* https://github.com/rust-lang/rust-clippy/issues/11124
* https://github.com/rust-lang/rust-clippy/issues/11144

Should fix those issues before enabling it for everyone.
