Unsatisfied version warnings from Scalprum

[gashcrumb]

Describe the bug

While testing the new backend system PR I did notice these warnings on the browser console:

I think this is due to a mismatch between the runtime version the host app is running and the version that a dynamic plugin is expecting, i.e. in this case we have several plugins being loaded that have been built against a released Backstage version but the host app is running with a pre-release version for these packages.

These warning indicate a potential runtime problem, however if there's no interface/API difference other than the package version there's no problem.

Some more time with the Scalprum docs is needed, as I recall there's a way to adjust/relax the accepted version range.
