fix: change ci param to errorbar in sns-catplot

[Busato]

What does this implement/fix?

Two tests were failing because of a deprecation of the ci parameter in sns.catplot function.

They were changed to errorbar instead that do the same thing when using None (both of the were using it)

CI failures appear unrelated, let me fix those in a separate PR then merge main into this branch, then should be good to go. Thanks in advance @Busato !

You can now also remove this line that I added https://github.com/mne-tools/mne-nirs/pull/525/files#diff-15c86dcddb07192eeb2d84db2a5dfca48e3837471adbbd9b3e05425b44fce485R49 if you want to make sure it has been fixed everywhere
