Add Support for GitHub App Installation Authentication in `GithubHook`

[kesugano]

Description

Enhance the GithubHook to support GitHub App installation authentication.

While the hook currently supports only token-based authentication, adding support for GitHub App installation authentication will provide a more secure option for Airflow users interacting with GitHub.

Use case/motivation

GitHub App installation authentication offers a more secure and granular permission model compared to personal access tokens. It allows for better audit trails and security practices, which are crucial for organizations managing complex workflows on GitHub.

By integrating this authentication method into GithubHook, Airflow users can leverage the benefits of GitHub Apps, such as fine-grained permissions, enhanced security, and improved automation capabilities within their data pipelines.
