We add the features version to the panel editor.
We had to refactor the panel to be able to
have the version with the table of content in
the same panel.
A bug was found in the version feature.
A 404 error appears sometimes, probably because
of Minio that does not keep enough versions.
We want to do a realease, so we will remove the
version feature for now.
We will have multiple Panel components in the future,
so we move it to the root of the components folder.
We refacto the Version Panel to use the new
Panel component.
When a user is on a page version, we will display
a button "Restore this version" near the title of
the page. It gives an obvious way to restore the
version of the doc.
To speed up pull request flow, put e2e tests
only mandatory for Chrome.
We still have tests for Firefox and Webkit,
but they are not mandatory.
They will still have to be checked regularly,
particularly during the deployment phase.
We can now replace the main version by another version.
Usefull either to come back to a previous version
or to update the main version with a new one.
