Merge #394

394: Reduce docker image size r=alallema a=sanders41

# Pull Request

With these changes I got ~ a 43% reduction in the final image size (1.55GB to 877MB). Note that depending on your local files present (virtual environments, etc) you may see slightly different numbers with a build, but it will always be significantly smaller.

## Related issue
Fixes #<issue_number>

## What does this PR do?
- Cleans up the `apt-get install` section
- Adds a `.dockerignore` file
- Removes the separate install of `pip3`. Because the image is `python:3.10.8-slim-bullseye` `pip` is already included by default

## PR checklist
Please check if your PR fulfills the following requirements:
- [x] Does this PR fix an existing issue, or have you listed the changes applied in the PR description (and why they are needed)?
- [x] Have you read the contributing guidelines?
- [x] Have you made sure that the title is accurate and descriptive of the changes?

Thank you so much for contributing to Meilisearch!
