Tool: enforce file name to use kebab-case in documentation content

[tbouffard]

IMPORTANT: Be aware of #422

This is advised in the Contributing documentation (https://github.com/bonitasoft/bonita-documentation-site/blob/b681fad6558299ae8027a749aa11121837a23d99/docs/content/CONTRIBUTING.adoc#file-names) but a lot of resources don't follow them.
This should be check as part of the repository content checks.
This will apply only to the branches of supported versions of the documentation.

Fixing the document content repositories first

Prior pushing this feature the document content repositories must be fixed.
cloud and bcd prefix some pages by categories. This naming comes from the time the documentation site was using Markdown content and there was no easy way to use subfolders. Antora modules should be used

• https://github.com/bonitasoft/bonita-cloud-doc/tree/67b9eeff6e50336e92f3e1bdf054e02844a70750/modules/ROOT/pages: cloud requires a full reorganization of the pages, probably by introducing Antora modules

Tasks

• implement a new step in the action - feat: Add a step to validate the filename actions#138
• add the check in the "contribution checks" workflow. Requires a release of the bonitasoft/actions first. We need an input to disable the step in content repositories where the page names haven't been fixed yet.
• document the commands used to detect file names that don't match kebab case in the content repositories
  • see non-kebab-case_pages.zip
  • the zip contains the results of the commands. For repositories with multiple versions, run the command on the branch of the oldest supported version
• fix filenames in content repositories
  • bcd? No longer updated so we may not want to update this content
  • bonita 2022.2 fix: rename pages to follow kebab-case bonita-doc#2875 / 2023.1+ fix: rename pages to follow kebab-case bonita-doc#2877
  • bpi Nothing to do
  • central Nothing to do
  • cloud refactor: introduce modules and rename pages to follow kebab-case bonita-cloud-doc#62
  • labs fix: rename pages to follow kebab-case bonita-labs-doc#163
