Merge bitcoin#28820: tests: Increase wallet_miniscript.py rpc timeout to 90 seconds

6559e4d tests: Increase wallet_miniscript.py rpc timeout to 90 seconds (Andrew Chow)

Pull request description:

  The signing test for the large miniscript can sometimes take longer than the 30 second timeout, depending on the load on my system. Increasing it to 90 seconds seems to be good enough.
