This removes the difference between high density images and other images regarding the pasting.
## Why
With this change, all images are clickable by default again. I don't think there is any problem regarding the img size because 1. it is the old behaviour, 2. the comment container already limits the size of the image.
## Alternatives
We can add an a-tag automatically when the user pastes an image. I do not prefer this because this adds a really long text (it's already bad with the img-tag) e.g.: `<a href="/attachments/28cf2254-13be-46c6-a433-efc77f556083" target="_blank"><img width="385" alt="grafik" src="/attachments/28cf2254-13be-46c6-a433-efc77f556083"></a>`
## Testing
1. Open an issue or pull request
2. Paste an image in the comment text box
3. The image should be pasted with valid Markdown syntax
