Description of problem:

• While labeling a pre-built read write many volume with "opendatahub.io/dashboard: 'true'" to make it visible through the AI dashboard, when creating a second workbench to reuse the same RWX PV, the PV isn't listed.

Prerequisites (if any, like setup, operators/versions):

• OpenShift AI 2.8.1
• OpenShift 4.14

Steps to Reproduce

• Create the PVC beforehand in OpenShift in the namespace corresponding to the RHOAI project, of RWX type
• Add label to PVC: opendatahub.io/dashboard: 'true' 
• Create a workbench 1 and use this PVC
• Create a second workbench and try to select the existing RWX PVC

Actual results:

• RWX PVC doesn't appear in the UI.

Expected results:

• Since PVC is RWX type, it should be possible to use it on multiple workbenches.

Reproducibility (Always/Intermittent/Only Once):

• Always

Build Details:
Workaround:

• Edit the notebook object of the second workbench and define the volumes section to point to the already existing RWX PVC
