Add a PAT for the eclipse-pde-bot user in the eclipse.pde repository

Summary

With a new Github workflow we would like to automate the process of applying version increments in the beginning of a release via

• https://github.com/eclipse-platform/eclipse.platform.releng.aggregator/pull/2352
• https://github.com/eclipse-pde/eclipse.pde/pull/1408

In order to make this work we need to have a Personal Access Token (PAT) with scope public_repo of the eclipse-pde-bot available in the secret store of the eclipse-pde/eclipse.pde repository. A secret name like PDE_BOT_PAT would be suitable.

This is similar to #4925 (closed).

If everything works well, we potentially need the same for multiple repos of the other Eclipse SDK organisations and their bot accounts

• https://github.com/eclipse-equinox/
• https://github.com/eclipse-platform/
• https://github.com/eclipse-jdt/

But I'll create dedicated tickets for them later.
