Updates the ibmq_dd_strategies_qss.ipynb notebook to not use the retired "ibmq_brisbane_qpu", and gets circuit duration estimates for ibmq_compile_*.ipynb to fix the recent failing notebook checks.

Note: After #1334, setting circuit durations is no longer done manually. Instead, as recommended, the notebooks use the .estimate_duration() method to determine the circuit duration value (at least until the duration setting is supported/needed in qiskit). This is necessary as qiskit's timeline drawer seems to call load_program() which then checks program._duration

This PR fixes a Brisbane QPU reference not updated in
#1339.

In addition, as IBM's Brisbane is retired, this PR drops most references
to it to make relevant code snippets more 'up-to-date'.

_Note: The `docs/source/apps/dfe/dfe_*.ipynb` are left as is with
retired IBM backends, as those endpoints are currently deprecated and
the notebooks are mainly intended as legacy archives._
