types-protobuf dependency is still on 3.x, while package supports protobuf 4.x

Hi, the title says it all.
The problem with types-protobuf 3.x for me is this issue https://github.com/python/typeshed/issues/5800.
In short: using types-protobuf 3.x overrides google cloud SDK typings, so I want to upgrade.

Can we change 
```
protobuf = ">=3.20"
types-protobuf = "~3.20"
```
to
```
protobuf = ">=3.20"
types-protobuf = ">=3.20"
```
?
