Provide an ascidoc attribute 'page-hide-components' to hide a list of components

[benjaminParisel]

To depreciate slowly a component listed in documentation site, we need sometime to hide an entry menu . We would like to hide one or more components in a specific couple component/version.

We want to stay the more generic as we can, so we imagine to declare an AsciiDoc attribute in the component descriptor file like:

asciidoc:
  attributes:
    page-hide-components: bcd, labs

:information_source: Put a list of component keys to be able to hide multiple entries.

• [x] https://github.com/bonitasoft/bonita-documentation-theme/issues/214
• [x] Release a new Theme version
• [x] Validate the new feature with the test content: #691

To use this new feature, we need to add in the antora.yml file:

asciidoc: attributes: page-hide-components: bcd, labs

In page-hide-components, the input waits a component key separated by a comma character.
