Build docker images for tokenizers main branch
:warning: Do not merge this PR!

PR 1/2: in order to run the full test suite (slow tests included), with the `main` branch of the `tokenizers` library, rebase this PR on `main`. Once the workflows have finished, head to PR 2/2 here: https://github.com/huggingface/transformers/pull/16712

---

This PR is one of two items to run the full test suite for the tokenizers current `main` branch.

In order to re-run, rebuild the docker images, publish them to the docker hub, and rebase this PR on the `main` branch of this repository.

Steps done in order to create this PR:
- Edit the dockerfiles so that they successfully install `tokenizers` from source in the container
- Edit the `build-docker-images.yml` action to:
    - Have it push these images to the Docker Hub.
    - Remove all non important images
    - Edit the identifier to contain `internal` as a prefix, and `tokenizers-main` as a suffix.
- Convert these images to private visibility so that it does not surprise users

These images will be built on each commit, so rebasing this branch on `main` will retrigger the workflow
