Rootstrap Pull request to Slack

Send Github pull request notifications to Slack.

• Each time a PR is created in your organization it will send a message to a specific Slack channel with a link to the PR and its technology emoji assigned.
• When the PR is merged it will add a merged reaction emoji.

• You can add \slack `This is a small pr @slack_user` at the end of the PR's description to add a message to the notification and to notify specific Slack users.

Make sure to use ` ` in the message in case the Slack user name is the same as someone's GitHub name, so the github user is not notified.

• It will not send a notification if the PR is a draft.
• It will remove the notification if the PR has an ON HOLD label and resend the notification when the label is removed.
