Tests: Revert timeout changes from gdb tests

There were additional `timeout=X` additions in #2382 which caused tests to fail randomly when a timeout was reached. The tests run through occationally, so it's not an infinite loop. But flakey tests are annoying and I don't see a reason for the timeout additions to the doctests for the core patch of that PR other than failing early during manual tests of new functionality. CI running smoothly is more important than fast failing during development on the gdb module imo.
