- [x] Closes #8055
- [x] User visible changes (including notable bug fixes) are documented in `whats-new.rst`

I've changed the example to include a 0 value which clearly shows that only NA values are ignored in the count. I've only modified the ""see also"" section for `count` since as mentioned in #8055 it is a bit of an outlier among the aggregation methods. I believe that this is not a long term fix since the single line summary of the method is of little use, but at least with this no one will have to take a look at the source code to quickly get what `count` does.

Feel free to correct any problems or suggest any changes, as I am quite new to contributing to projects like this and have little idea of what I'm doing :sweat_smile: ","{""url"": ""https://api.github.com/repos/pydata/xarray/issues/8057/reactions"", ""total_count"": 0, ""+1"": 0, ""-1"": 0, ""laugh"": 0, ""hooray"": 0, ""confused"": 0, ""heart"": 0, ""rocket"": 0, ""eyes"": 0}",,,13221727,pull
