   Coming from #28414 comment Same thing also for descriptorprocesspsbt.

   Before this PR descriptorprocesspsbt returns a boolean complete which indicates that the psbt is final, users then have to call finalizepsbt to get the hex encoded network transaction.

   In this PR if the psbt is complete the return object also has the hex encoded network transaction ready for broadcast with sendrawtransaction.

   This save users calling finalizepsbt with the descriptor, if it is already complete.

2. rpc: `descriptorprocesspsbt` return hex encoded tx

   If processed psbt is complete return hex encoded network
   transaction in the output.

3. test: check `descriptorprocesspsbt` return hex encoded tx

   Test that if the processed psbt is complete the hex encoded tx
   is returned and remove unneccessary rpc call to finalize the
   psbt.

   Thanks, this basically means the same thing IMO, resolving this.

   nit: might be cleaner to not re-use variable names processed_psbt and decoded but im not sure how strict we are about stuff like that in tests

   Thanks for your review! Will use distinct variable names in future contribution, but happy to update this if another reviewer ask for it.
