fix: address issue with computeclass tables not converting properly

[tylerslaton]

This fixes an issue where acorn offerings computeclasses and kubectl get clustercomputeclasses would fail with the following error:

  ✗  ERROR:  template: :1:39: executing "" at <memoryToRange .Memory>: error calling memoryToRange: object passed is not a ComputeClassMemory struct

This was due to a recent change where the Memory struct on apiv1.ComputeClass and adminv1.ClusterComputeClass are now different. The fix is to check for both types and process them accordingly when converting values into a table.
