author_value
If the PR author is a also an eligible reviewer, you can count their approval automatically (even if the host platform doesn't allow them to approve a PR).
By default, author_value is 0. Typically you will use 1 to count the author as one approval, but you can use bigger numbers to give the author more weight in the approval process.
