BindingAction equality changed in 0.55.0

[lukeredpath]

Description

I'm trying to upgrade to 0.55 and there seems to have been a change in the implementation of BindingAction<T> equality, because I have some tests that .receive a binding action which fail due to them not being equal.

Checklist

• [ ] I have determined whether this bug is also reproducible in a vanilla SwiftUI project.
• [ ] If possible, I've reproduced the issue using the main branch of this package.
• [X] This issue hasn't been addressed in an existing GitHub issue or discussion.

Expected behavior

When using store.receive(.set(\.$foo, "bar")) in a test, if that action is received the test should pass.

Actual behavior

The test fails, complaining that the actions were not equal although they have no differences.

On further inspection in the debugger, I set a breakpoint inside BindingAction.== and observed this in one of my tests:

(lldb) po rhs
▿ BindingAction<State>
  - keyPath : \State.$isFocused
  - set : (Function)
  ▿ value : AnySendable
    - base : true
  - valueIsEqualTo : (Function)

(lldb) po lhs.keyPath == rhs.keyPath
true

(lldb) po lhs.valueIsEqualTo(rhs.value)
false

(lldb) po lhs.value
▿ AnySendable
  - base : true

(lldb) po rhs.value
▿ AnySendable
  - base : true

It looks like the issue is that the == implementation is passing the AnySendable into the valueIsEqualTo function but it is expecting the underlying base value.

  public static func == (lhs: Self, rhs: Self) -> Bool {
-    lhs.keyPath == rhs.keyPath && lhs.valueIsEqualTo(rhs.value)
+    lhs.keyPath == rhs.keyPath && lhs.valueIsEqualTo(rhs.value.base)
  }

Ah, turns out this is fixed on main.

Is there any chance of a 0.55.1 release with this fix please?
