Default publisher set to openZIM

[AKACHI-4]

Description

This pull request sets the default publisher to openZIM in the /scraper/src/fcc2zim/entrypoint.py file.

Related Issue

Fix #31

Observations

There are two files where we explicitly set the publisher to openZIM:

• In test_scraper.py, the value is correctly set to openZIM.
  

• In entrypoint.py, it was originally set to OpenZIM, but has now been corrected to openZIM.

LGTM

Some remark for next PR:

• you have to add Fix #xxx in your first comment (instead of related to issue #xxx) to link the PR with the corresponding issue (see https://docs.github.com/en/issues/tracking-your-work-with-issues/linking-a-pull-request-to-an-issue
• you must not commit your changes to a main branch but to a newly created branch (this will be especially important one we will give you developer permissions on this repo) ; the newly created branch should be name according to the intent of the changes, e.g. default_publisher

Please read https://github.com/openzim/overview/wiki/openZIM-code-contribution-workflow with a lot of attention to all details.
