Website bug: fix docs REST API table Markdown

[mike-j-thomas]

• Markdown for this parameters table needs fixing https://fleetdm.com/docs/using-fleet/rest-api#list-labels

• Anchor link https://fleetdm.com/docs/using-fleet/rest-api#get-labels-sumary is missing an "m" in summary.

@mike-j-thomas, I'm looking at the table and it seems to be rendering properly. Could you be more specific about what's wrong with it?
I fixed the link to read "summary" instead of "sumary."

I found the table you were talking about. It looks much happier now. I'm awaiting @chiiph's review.
