Issue:
Missing function to update dependabot alerts
Reading [this file](https://github.com/google/go-github/blob/fd33b81221685302178ba197dbabe71326ca9051/github/dependabot_alerts.go
) there is no reference to a function to [Update a Dependabot Alerts](https://docs.github.com/en/rest/dependabot/alerts?apiVersion=2022-11-28#update-a-dependabot-alert
)

I would like to implement it but I am opening an issue first to ask if there is any other way to do it that I am currently missing.

Pull request:
Add dependabot alert update endpoint
Adds support for https://docs.github.com/en/rest/dependabot/alerts?apiVersion=2022-11-28#update-a-dependabot-alert.

Closes #2922. This is also a dupe of #2955, which hasn't seen action in a few weeks and had build errors.
