Revert "Fix QuantumCircuit.assign_parameters docstring (Qiskit#6546…

…)"

This PR included a deprecation removal which was invalid as not enough
time has passed. The deprecation occured in 0.17.0 which is not eligible
for removal until the 0.19.0 release. This PR can be repropoposed after
0.18.0 is released and quickly merged into 0.19.0.

This reverts commit 09f9c10.
