Allow AWS codeartifact login with uv

### Describe the feature

uv is a popular tool to manage dependencies in Python project. Right now it is impossible to login with aws codeartifact +uv.
Since pip is supported, the common usage is:
1. login with pip
2. copy the url from the pip configuration to the uv configuration (which indicates the change is not extremely complicated to make)
3. uv pip install ...

### Use Case

```
aws codeartifact login --tool uv
```
and then doing:
```
uv pip install ...
```
