* Repository maintenance: add GitHub Repo Gardening action

The Repo Gardening action is a tool that one can use to automate some of the tasks that you can perform to monitor activity in your repository.
https://github.com/marketplace/actions/repository-gardening

It includes different tasks, that can be enabled based on your needs.

This commit gets us started with the action by enabling a few tasks.

- This action relies on a few secrets that have already been added to this repo.
- Of note, `gatherSupportReferences` and `replyToCustomersReminder` aren't too useful right now, but will become useful once the plugin is released on WordPress.com and once we start receiving feedback from WordPress.com site owners.
- The `flagOss` task will point to #fediverse for now. This can be updated later on.
- I've added mapping for our 2 block directories, but that mapping can be extended for more automatic labeling later on.

* Add issue templates

This is typically only the case for sites using a custom version of WordPress, like ClassicPress.

One can now deactivate the blocks registered by ActivityPub like so:

```
add_filter( 'activitypub_site_supports_blocks', '__return_false' );
```

Fixes #440

Also add typography control

Co-authored-by: Matthias Pfefferle <pfefferle@users.noreply.github.com>

This will prevent the issue of attaching images that don't were uploaded to the post but not used in the post

The post needs to be using blocks to get the introspection required.
