Geo docs: Add "Releasing the feature" section to Self-Service Framework

See merge request gitlab-org/gitlab!43249

If the relation is grouped, Rails returns Hash: { group-key => count }
https://apidock.com/rails/ActiveRecord/Calculations/count

Since batch_count expects Integer in order to sum the counts up,
we receive an error. We can sum up the Hash's size in this case.

The HTML spec in https://www.w3.org/TR/html52/syntax.html#in-body
mentions: Newlines at the start of textarea elements are ignored as
an authoring convenience.

This causes issues with task list parsing because the lines are now off
by one.

We didn't have this problem with issues because the textarea value was
set in Javascript with Vue.

This also removes instances of js-task-list-field which are actually
unused.
