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.
