Fix dask EWA code not creating unique dask task names for different target areas

[djhoese]

I've always tested the new algorithm with only one target, but once it was thrown into Polar2Grid we quickly realized that multiple targets was a problem. Luckily because of my map_blocks PR last week I knew to look at the dask task names for the issue.

• Tests added
• Tests passed
• Passes git diff origin/main **/*py | flake8 --diff

Oh I should note I also added a small fix to the deploy CI so it doesn't run on all types of "published" events. It was something I noticed during the last release that I forgot to push then.
