Add support for library publication

[flatombe]

This issue is for the implementation of shape 2025.04/add_support_for_library_publication.adoc

• Frontend: We will add a link from the 'help' menu (top right corner) to $baseUrl/libraries (the Sirius Web page that displays all published libraries)
• Backend: We will contribute an IOmniboxCommandProvider for SysML projects, populated with 1 command for publishing a SysML project as a library.
• Backend: We will contribute an ILibraryPublicationHandler that performs the publication as a library of an input SysML project.
• Frontend: We will add to the default palette command registry a new command to trigger the publication as a library of the contextual SysML project. We might reuse parts of the Sirius Web frontend for publishing studio projects as libraries (e.g. dialog that prompts for library name and version).

Note that this feature draws inspiration from ongoing work in SW : eclipse-sirius/sirius-web#4598
It can only be tackled once the work has been integrated in the SW version consumed by SysON
