Tutorial bug report (mainly download failure from osf)

[JizeZhangPsych]

0. osl install instructions, https://raw.githubusercontent.com/OHBA-analysis/osl/main/envs/linux-full.yml, conda would stuck at solving dependencies; remove the version limit for pip, vtk and pyvista is recommended, as directly running conda install python=3.8.16 pip=23.3.1 vtk=9.1.0=*osmesa* pyvista=0.38.5 would also lead to stucking;
1. source-recon-coreg.ipynb, the first code block, line 2, sys.command is not a valid function in python. please use os.system / subprocess.run() / ! trick in ipynb instead;
2. source-recon-coreg.ipynb, the first code block, osf -p zxb6c fetch SourceRecon/data/notts_2subjects.zip would fail to download anything from osf;
3. source-recon_subject.ipynb, the first code block, osf -p zxb6c fetch SourceRecon/data/wake_hen.zip would fail to download anything from osf;
