Update the changelog update documentation
I just started working on updating the changelog. Hopefully the docs are a bit clearer now?

If let else mutex
changelog: Adds lint to catch incorrect use of `Mutex::lock` in `if let` expressions with lock calls in any of the blocks.
closes: #5219
Implement unsafe_derive_deserialize lint
Added `unsafe_derive_deserialize` lint to check for cases when automatically deriving `serde::Deserialize` can be problematic, i.e. with types that have methods using `unsafe`.
Closes#5471
changelog: Add lint [`unsafe_derive_deserialize`]
Fix issue #2907.
Update the "borrow box" lint to avoid recommending the following
conversion:
```
// Old
pub fn f(&mut Box<T>) {...}
// New
pub fn f(&mut T) {...}
```
Given a mutable reference to a box, functions may want to change
"which" object the Box is pointing at.
This change avoids recommending removing the "Box" parameter
for mutable references.
changelog: Don't trigger [`borrow_box`] lint on `&mut Box` references
Cleanup: `node_id` -> `hir_id`
This removes some more `node_id` terminology from Clippy and replaces one occurrence of `as_local_node_id` with `as_local_hir_id`, which should be doing the same for that particular case.
changelog: none
Don't trigger toplevel_ref_arg for `for` loops
The lint suggests turning `for ref x in 0..10 {` into `for ref x in let x = &0..10; {`.

Add lint named implicit_saturating_sub
Fixes: #5399
I've made a basic skeleton of the lint, would love more feedback on how to make it better.
changelog: Add lint [`implicit_saturating_sub`]
fix redundant_pattern_matching lint
- now it handles `while let` case (related to #5462)
- better suggestions in `if let` case
changelog: Fix suggestion in `redundant_pattern_matching` and also apply this lint to the `while let` case
add lint futures_not_send
changelog: add lint futures_not_send
fixes#5379
~Remark: one thing that can (should?) still be improved is to directly include the error message from the `Send` check so that the programmer stays in the flow. Currently, getting the actual error message requires a restructuring of the code to make the `Send` constraint explicit.~
It now shows all unmet constraints for allowing the Future to be Send.
