In all our Python examples, show how to pip install rerun-sdk (#2221)

### What
Changed all our examples from

```py
import rerun as rr
```

to

```py
import rerun as rr  # pip install rerun-sdk
```

A lot of people only look at examples, and we want to make sure they
don't fall into the trap of `pip install rerun`
