Speed up dijkstra_bankers_algorithm.py

[tianyizheng02]

Describe your change:

Contributes to #9718

Speeds up other/dijkstra_bankers_algorithm.py... apparently there was a time.sleep(1) call in the code for some reason. Also shortened the name of the file from dijkstra_bankers_algorithm.py to just bankers_algorithm.py (the referenced sources and the file documentation all refer to the algorithm as just the "banker's algorithm").

... and the file's no longer on the list. I can't believe the only reason why it was so slow was because there was a sleep call in the code 💀
