Description
Originally from @SNvMK in https://github.com/microsoft/vscode/issues/120734
So, in python 3.10, there is match/case syntax. Currently, it is just white words(for monokai). I'd like if you add highlight for this. Thanks

```python
a = 'world'
match a:
case 'world':
print('Hello!')
case _:
print('I dont know you!')
```
Currently the `match` and `case` are only tokenized as `source.python`.

Research direction
Start by locating the Python tokenization rules used by this syntax highlighter and compare the handling of the match/case example in the issue with existing keyword rules. Done means match and case receive appropriate syntax highlighting in the supported editors, without changing unrelated Python highlighting.
