[docs-only] Text fix for thumbnail README.md

Browse Source 
References: #7409 (feature(thumbnails): add the ability to define custom image processors)
The `Thumbnail Processor` section needed an update to clarify the usecase and behaviour. In addition, the list of sizes above now shows as in a single line each and not in one line.

## Thumbnail Processors
Image generation can be configured by defining different processors, following processors are available:
Normally, an image might get cropped when creating a preview, depending on the aspect ratio of the original image. This can have negative
impacts on previews as only a part of the image will be shown. When using an _optional_ processor in the request, cropping can be avoided by
defining on how the preview image generation will be done. The following processors are available:
* `resize`
* `fit`
* `fill`
* `thumbnail`
To apply one of those, a query parameter has to be added to the request, e.g. `?processor=fit`
To apply one of those, a query parameter has to be added to the request, like `?processor=fit`. If no query parameter or processor
is added, the default behaviour applies which is `resize` for gif's and `thumbnail` for all others.
