Updating the allow_update_branch setting for a repository

README

# Updating the setting to update branches when there is a build incident

## Initial rollout 



### Why?

A very common thing that happens at Gusto is a build incident due to some flakiness or intermittent database network issue. 
A developers first instinct is to update to main to see if the issue has been resolved. Many times this results in merging to 
main several times, costing the company money.


### What?

We can leverage two approaches: Github REST API and Octokit.rb (wrapper around the github API)

> Using REST API

```sh
curl --location --request PATCH 'https://api.github.com/repos/org/repo' \
--header 'Accept: application/vnd.github+json' \
--header 'X-Github-Api-Version: 2022-11-28' \
--header 'Content-Type: application/json' \
--header 'Authorization: Bearer ' \
--data '{
    "allow_update_branch": false
}'
```

> Using Octokit

```ruby
client.edit_repository('org/repo', allow_update_branch: true)
```

One caveat is the API token that is used needs to have read and write access to Repository access permissions in order to be able to work
