MAINT: Fix deprecated seaborn function calls

Fix deprecated `seaborn` function calls: use `displot` or `histplot`
where applicable instead of `distplot`, since the latter will be removed
in `seaborn` v0.14.0.

Adapt the corresponding calls where necessary adding reasonable keyword
argument values.

Fixes:
```
This function has been deprecated and will be removed in seaborn v0.14.0.
It has been replaced by :func:`histplot` and :func:`displot`,
two functions with a modern API and many more capabilities.
```
