CompatHelper: bump compat for BlockSparseArrays to 0.5 for package test, (keep existing compat)

[github-actions]

This pull request changes the compat entry for the BlockSparseArrays package from 0.4 to 0.4, 0.5 for package test.
This keeps the compat entries for earlier versions.

Note: I have not tested your package with this new compat entry.
It is your responsibility to make sure that your package tests pass before you merge this pull request.
