Description
From @BornForFever in https://github.com/microsoft/vscode/issues/94999
The walrus operator `:=`(an operator to allow you to make assignments in an expression, see [PEP 572](https://www.python.org/dev/peps/pep-0572)) is highlighted as 2 different colors. And I tried inspecting tokens and scopes, and found that `:` and `=` were treated as 2 tokens.

Research direction
No source file or test is named in the issue. Start by locating the Python grammar and token-scope rules responsible for `:=`, then compare the scopes produced for `if m := x` with the intended single walrus-operator token; done means the operator is highlighted consistently and its colon and equals signs are no longer separate tokens.
