[ResourceManager] Local extensions overrides (Azure#47366)

The focus of these changes is to fix the project reference CI leg which is
failing due to in-process work to bump extension package dependencies.  These
packages are being bumped locally to force transitive dependencies to play nice
while we work on the central updates.
