Release 1.0.0 - Githubissues

This issue serves as a checklist for the release event.

[x] Check that dependencies have been updated to latest version (especially python-scraper lib)
[x] Adjust version in __about__.py to x.x.x (remove -devx suffix)
[x] Update Github milestone to match the issues that will be released
[x] Close Github milestone
[x] Update the Changelog so that it is in line with the content of Github milestone
[x] Push a tag on Github named vx.x.x
[x] Create a Github release, pointing to the tag, with the Changelog of this release
[x] Publish the Github release (this will trigger the CI, if the CI fails and you have to push a minor fix which does not justify to create a new version, you will have to delete the release and re-create it from scratch)
[x] Check that version is published as a Github release at https://github.com/openzim/freecodecamp/releases
[x] Check that version is published on Github Container Registry at https://ghcr.io/openzim/freecodecamp and tagged latest
[x] Check that version is published on Pypi at https://pypi.org/project/fcc2zim/
[x] Create a new Github milestone with the next minor version incrementaly
[x] Create a new Github issue attached to this milestone with this checklist inside
[x] Create new ## [Unreleased] section in Changelog (placeholder for future entries)
[x] Adjust version in __about__.py to `x.y.z-dev0 (next expected release in the pipe)
[x] Push both changes to main branch
[x] Inform rgaudin/benoit74 (on #scrapers on slack) that a new release is ready to use so that they will update Zimfarm recipes (mention release version / tag name)
[x] If needed, open a PR on Zimfarm to add support for new CLI parameters of interest
