[Spark] Pin the pip version to 24.0 to get around the version for…

…mat requirement (#3302)

... enforced by the `pip` from `24.1`

Recent `delta-spark` [CI
jobs](https://github.com/delta-io/delta/actions/runs/9628486756/job/26556785657)
are failing with the following error.
```
ERROR: Invalid requirement: 'delta-spark==3.3.0-SNAPSHOT': Expected end or semicolon (after version specifier)
    delta-spark==3.3.0-SNAPSHOT
               ~~~~~~~^
```

Earlier
[runs](https://github.com/delta-io/delta/actions/runs/9526169441/job/26261227425)
had the following warning
```
DEPRECATION: delta-spark 3.3.0-SNAPSHOT has a non-standard version number. pip 23.3 will enforce this behaviour change. A possible replacement is to upgrade to a newer version of delta-spark or contact the author to suggest that they release a version with a conforming version number. Discussion can be found at pypa/pip#12063
```

Pinning the `pip` version to `23.2.1` to let the jobs pass. We need to
find a long-term solution on the version of the PyPI generated to avoid
this issue but it is a bit complicated as the `delta-spark` PyPI also
depends on the delta jars with the same version as the PyPI package
name.
