Links in documentation to github codebase are broken as long as technical branche is not created

[benjaminParisel]

A lot of links in this page send the user to a not found page of GitHub.

In this link, the bonitaTechnicalVersion is used to redirect on the GitHub branch. However, for the latest maintenance version and for the version on development, we use master/dev branch convention name.

That's why we are redirected to the 404 GitHub page.

To fix this issue, we can:

• [x] Create and use a new antora attribute, reserved exclusively for this behavior, and set the value as master/dev. (Don't forget to update it when a new release is created)
• [x] Another idea ?

note: In the config (antora.yml), we use some reusable attributes bonitasoft-docker-repository: '{bonitasoft-registry}/docker'. We can perhaps reuse this mechanism

:heavy_check_mark: This page contains some broken links only because the source code is moving to another repository. We will make this PR on documentation content to manage this issue. So i can close this issue.
