fix: Make build compatible with new GDAL container TDE-1179 (#971)

#### Motivation

Make build compatible with [GDAL 3.9
container](#962).

#### Modification

- Use multi-stage build to avoid including build tools in the final
image.
- Install Poetry using pipx, as
[recommended](https://python-poetry.org/docs/#installation).
- Use a different working directory in the first stage, to avoid the
possibility of confusing the two or unintended interactions between
them.
- Use a virtualenv to avoid clobbering OS packages.

#### Checklist

- [ ] Tests updated (N/A)
- [ ] Docs updated (N/A)
- [x] Issue linked in Title
