081641249e README: fix lit count line 
It looks like after changing to "there are more than 120 lints", an older PR was merged
and resolving merge conflicts this was changed back to "there are 123 lints" causing the update-script to silently fail.

Changed back the README.md back to the new format fixes the problem.

1d4dd3d428 Auto merge of #5439 - rokob:lock-await, r=Manishearth 
Lint for holding locks across await points

Fixes #4226

This introduces the lint await_holding_lock. For async functions, we iterate
over all types in generator_interior_types and look for types named MutexGuard,
RwLockReadGuard, or RwLockWriteGuard. If we find one then we emit a lint.

changelog: introduce the await_holding_lock lint

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

2efc2d6366 Auto merge of #5491 - smklein:borrowed_box, r=flip1995 
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
