Change the docs markdown so that flag names will be h4 headers. Sphinx will automatically add anchors to headers. Add css to make sure the flag names are not to big compared to the text. The man pages also still renders fine but it looks a bit different. Signed-off-by: Paul Holzinger <paul.holzinger@web.de>

## NAME
|
|
podman-image-prune - Remove all unused images from the local store
|
|
|
|
## SYNOPSIS
|
|
**podman image prune** [*options*]
|
|
|
|
## DESCRIPTION
|
|
**podman image prune** removes all dangling images from local storage. With the `all` option,
|
|
you can delete all unused images. Unused images are dangling images as well as any image that

does not have any containers based on it.
|
|
|
|
The image prune command does not prune cache images that only use layers that are necessary for other images.
|
|
|
