Update README.md

• change rmmod to modprobe -r per advice here: https://www.computerhope.com/unix/rmmod.htm#desc
• reorder dvb_ modules to ensure proper unloading with consideration to dependency chains

These need to be removed in a certain order. See https://discord.com/channels/734090820684349521/734090821250580564/1081023241633660948

could you update your commit to reflect that? thanks!

Also it looks like we should use modprobe -r rather than rmmod according to your link?

Order fixed.

Yes, apparently modprobe -r is a more robust method of unloading the modules. We can explore the additional flag of --remove-dependencies but I didn't include that here at the moment in order to have the change be incremental and handle one module at a time still as rmmod had been doing.
