Rename and inline refactor did not recognize match-cases statements as variable assignment

[lieryan]

Describe the bug

The match statement allows pattern capture which effectively acts like an assignment statement. Currently they are not recognised as assignment statement that can define a variable.

To Reproduce
Steps to reproduce the behavior:

1. Code before refactoring:

x = [1, 2, 3]
match x:
    case [1, *_] as old_name_1:
        print(old_name_1)
    case [2, *old_name_2]:
        print(old_name_2)

2. Describe the refactoring you want to do: rename old_name_xxx to new_name_xxx

3. Expected code after refactoring:

x = [1, 2, 3]
match x:
    case [1, *_] as new_name_1:
        print(new_name_1)
    case [2, *new_name_2]:
        print(new_name_2)

4. Describe the error or unexpected result that you are getting
