**Description**
While researching how to create a chart for [graylog
open](https://graylog.org/products/source-available/), I noticed that
there was a typo in the annotation: **truecharts.org/categories**. I
fixed all instances of this typo in the repo. In addition, I addressed
all other instances of the word category and categories (case
insensitive) for all code (shell scripts), comments, markdowns, and
filenames.
