619327957,MDExOlB1bGxSZXF1ZXN0NDE4ODc5MTU3,4067,make text wrap width an argument in label_from_attrs,20617032,closed,0,,,4,2020-05-15T23:44:09Z,2023-03-26T20:06:29Z,2023-03-26T20:06:28Z,NONE,,0,pydata/xarray/pulls/4067,"label_from_attrs used textwrap.wrap with a default wrap width of 30,
this commit changes label_from_attrs to instead take an argument
wrap_width that specifies the wrap width.

context: I find the label_from_attrs function useful for plots that I make using pyplot, but needed to change the text wrap with. 

I am new to contributing to projects like this so bear with me.  I only had the mypy and flake8 linters and figured that was good enough for a minor change like this. And I didn't see label_from_attrs in the api document so just added a line to whats-new.rst

 - [x] Passes  mypy . && flake8`
 - [x] Fully documented, including `whats-new.rst`
