Description

This configuration was supported via .env. However, it has not been added to the GitHub transformation page in the config-ui's blueprint creation flow.

# GITHUB_PR_BODY_CLOSE=(?mi)^.*(fix|close|resolve|fixes|closes|resolves|fixed|closed|resolved)[\s]* .*\d+
GITHUB_PR_BODY_CLOSE_PATTERN=
# GITHUB_PR_BODY_NUMBER_PREFIX="(#|https:\/\/github.com\/%s\/%s\/issues\/)"

Use case

As a project maintainer, I want to see the number of different types of issues (features/bugs) a PR closes. Then I can calculate dev resources spent on different types of work.
