Corrected version of gwpy from 3.0.4 to 3.0.5

Hi Simone checking the errors it seems that we should correct the gwpy version also in the tutorial 3.2:
Version issues: Failed: Tutorials/Day_3/Tuto_3.2_Parameter_estimation_for_compact_object_mergers.ipynb has a version mismatch in gwpy: 3.0.4 != 3.0.5

And also it would be good if you could correct these two spelling errors:
./Tutorials/Solutions/README.md:9: explanantion ==> explanation
./Tutorials/Day_1/Tuto_1.4_Generating_waveforms.ipynb:187: precess ==> process
and
