`RepositoriesMode.FAIL_ON_PROJECT_REPOS` does not work with legacyforge plugin

[lukebemish]

Applying the net.neoforged.moddev.repositories plugin in the settings.gradle and setting dependencyResolutionManagement.repositoriesMode = RepositoriesMode.FAIL_ON_PROJECT_REPOS, while functioning fine with the normal moddevgradle plugin, will fail if the net.neoforged.moddev.legacyforge plugin is applied in a project as that plugin sets a project repository: https://github.com/neoforged/ModDevGradle/blob/main/src/legacy/java/net/neoforged/moddevgradle/legacyforge/internal/LegacyForgeModDevPlugin.java#L73-L76.
