Generate API token valid for longer period than 1 hour

### What feature do you want to see added?

We have a set of Jenkins jobs that run for up to two hours. These tests store credentials in a Managed File that agents use to access several resources. However, because the agents run for more than 1 hour, the initial set of calls to GitHub succeeds but the final one fails because the token has already expired.

From the documentation, it seems that Jenkins is using Authenticating as a GitHub App installation, using tokens that are valid for only 1 hour. Because we store that credential in a Managed File in a longer duration run, we don't have a chance to request a new token.

From GitHub App documentation, there's a possibility to use User access tokens created by a GitHub App which will expire after eight hours by default.

Our goal is to use GitHub App token as replacement for service/bot accounts which are used in automation, but the 1 hour restriction is too limiting for us. Is there any way to overcome this issue?
