List of errors discovered when creating a pipeline.

[gagnonanthony]

While creating nf-pediatric, I encountered minor typos/errors in the module. I place a list here in case someone wants to fix them before I do:

• Add a touch bounding_box.pkl in the stub of betcrop/cropvolume. (@arnaudbore)
• For some reason, freesurfer/synthbet:1.6.0 did not work on both Mac and Linux, I changed it to freesurfer/freesurfer:7.4.1, and it worked fine. (@ThoumyreStanislas) It also works with freesurfer/synthstrip:1.5.
• Add automatic shell detection and selection in image/powderaverage. (@gagnonanthony)
• Fix the first_suffix argument in image/resample. (@gagnonanthony)
• Add the correct prefix_topup in the stub section in the topup module. (@Manonedde)
• Remove the .py extension in N4BiasFieldCorrection in the stub of preproc/n4. (@arnaudbore)
• Update reconst/frf to the correct scil version. (@ThoumyreStanislas)
• Fix ANTs version in registration/anattodwi. (@gagnonanthony)
• Split affine and warp in registration/antsapplytransforms + fix version. (@gagnonanthony)
• Update segmentation/freesurferseg versions. (@gagnonanthony)
• Update segmentation/fsreconall versions. (@gagnonanthony)
• Update versions in utils/extractb0. (@Manonedde)
