This removes the extra space in front of the new /support image. Thank you for the suggestion @sgugger ! 

Got too excited to merge the previous image update and missed this housekeeping fix. 
@sgugger I don't think I agree with the suggestion. This is not my area of expertise 😅, but I think HTML elements should be indented (e.g. `<img>` child element indented within the `<a>` parent element), even on a markdown file. <|||||>The docs for this PR live [here](https://moon-ci-docs.huggingface.co/docs/transformers/pr_17548). All of your documentation changes will be reflected on that endpoint.<|||||>It wasn't indented before the first PR and was working perfectly fine.<|||||>Yes, it works in either case. I think it's usually suggested to use indentation in HTML elements for readability purposes. No strong opinion on this, though!<|||||>This issue has been automatically marked as stale because it has not had recent activity.
