Multitenant: new versions of ORDS (later than 23.4) dont work

[ilfur]

When trying to create a new PDB , I get an error in a kubernetes event/ORDS error: "new_pdb_name is a mandatory field". The thing is that the REST API for managing multitenant databases changed a bit with ORDS 24.1 and above. The parameter for creating new PDBs is now called "new_pdb_name" instead of the former "pdb_name". I suggest to use both parameters to support older and newer ORDS versions... and to check for other deprecations too :-)
