Add Comments to CSV export

[freezingDaniel]

While trying to find out for which reason I "fail" my habit most often I wanted to check and sum up the comments I leave on a specific habit.

Given that I did not want to click through every day manually I exported the CSV just to discover that the comments are not part of it.

Checkmarks.csv
is: 2023-09-17,2
Expected: 2023-09-17,2,comment

I agree. I don't understand the use of comments if i can't export them in the end.

I believe this is a duplicate of #1567. So please comment/vote there also.
