Wrong VSM migration version

[GlennPlou]

In OD 11.9, when importing VSM created in development runtime with all Sirius plugins (since 7.4.0) - including experimental features - we get the following error:

An internal error occurred during: "Loading models".
The modeling project "sample" is invalid: Problem during loading models: The viewpoint specification model (platform:/resource/sample/My.odesign) can not be loaded because it comes from a more recent Sirius release.
VSM version is: 15.4.0.202401051836
Last Sirius migration version is: 12.0.0.2017041100

It is raised because OD doesn't include ELK plugins by default. Migration version 15.4.0.202401051836 is defined in org.eclipse.sirius.diagram.elk.migration.description.ELK090MigrationParticipant, so if the user didn't installed the plugin org.eclipse.sirius.diagram.elk, its last migration version would be 12.0.0.2017041100.

Another related issue: In Eclipse 2024-09, I installed Sirius 7.4.3 with the update site, checked all features except ELK-related features and dependencies. However, some elk plugins have been installed, although ELK features are not installed. So I have the VSM-version-issue even though I haven't installed ELK features.

In this case, we should see what caused the installation of the ELK plugins. But since the ELK plugins were installed, it is "normal" to have the corresponding migration participant.
