MAINT: Remove deprecation for kind

[larsoner]

Post-release deprecation resolution

@drammock there is a remaining one in mne/viz/topomap.py, feel free to take care of it by pushing commits here or by opening a separate PR

[drammock]

@larsoner there were a TON of things to remove; thanks for noticing / reminding that I forgot to do this after release.

nb: this removal is not a mistake; the whole function was added in 1.2 so no need to point out that this param was also added then.

Just BTW - why was it decided to remove vmin and vmax and use vlims for topomaps? As long as I remember I used vmin and vmax in mne and I don't think I ever encountered vlims in topomap plotting.

Just BTW - why was it decided to remove vmin and vmax and use vlims for topomaps?

There are some topomap functions where vlim='joint' is an option (to compute vmin/vmax automatically and have it be the same for all subplots). I think plot_projs_topomap was the original use case for this. Since the goal was to standardize the param names across all topomap-generating funcs/methods, switching them all to vlim was the simplest way.

Ok, I get it now :)
