[FEAT]: Revoke an installation access token

[Danielku15]

Describe the need

Octokit is missing an API for https://docs.github.com/en/rest/apps/installations?apiVersion=2022-11-28#revoke-an-installation-access-token

I'd say it should be added here:

• https://github.com/octokit/octokit.net/blob/main/Octokit/Clients/IGitHubAppInstallationsClient.cs
• https://github.com/octokit/octokit.net/blob/main/Octokit/Clients/GitHubAppInstallationsClient.cs

We want to login/logout cleanly similar to https://github.com/actions/create-github-app-token/blob/main/lib/post.js#L31C27-L31C46

SDK Version

Octokit.net 13.0.1

API Version

REST API 2022-11-28

Hello, you can revoke it using revokeInstallationAccessToken() method.

eg: await octokit.apps.revokeInstallationAccessToken();

make sure to instantiate octokit with createAppAuth authStrategy before this.
