Summarise multiple commits

[takahser]

Currently this bot is providing suggestions for each file change in a commit. However, I was wondering if it was possible to summarise the whole PR to give an overview what it does instead.

Currently, we do not offer support for this feature. It is important to take into account the size of the pull request, as it might exceed the token limit for GPT to effectively review it.

@anc95 I understand, thanks for the feedback!
