A few commands currently have a short option -a for the option asAdmin. As discussed here, #4107 (comment), the specs didn't introduce a short option and it isn't directly necesary to create one for asAdmin. With this, let's remove this short option for the following commands:

• pp card clone
• pp card get
• pp card list
• pp dataverse table get
• pp dataverse table list
• pp dataverse table remove
• pp environment get
• pp environment list
• pp solution get
• pp solution list
• pp solution publisher get
• pp solution publisher list
• pp solution publisher remove
• pp solution remove
