FR: Fix compatibility with templates containing YAML

[brimwats]

My Map Location template has YAML in it already. So when I use the geolocation note command I get this

---
location: [43.096972,-71.465378]
---

---
Metadata: 
fileClass: Thing
ThingType: Map
Created: 2022-06-25 07:50
aliases: []
tags: [🗺️]
---

this is obviously bad YAML, so it would be great if location: was moved into the current YAML, or if we could create a template in Map View's settings, like AidenLX Folder Note allows someone to add a template in

[esm7]

Indeed didn't take this into account! Will fix.
