The minify-map-json action is causing itself to run every time its PRs are merged.
This hopefully will stop that happening, but ignoring anything with an 'automated' label and then applying that label when pushing the PR
- fix incorrect key name in merge file (json_data['objects']['boundaries.geo'] rather than json_data['objects']['boundaries'])
- don't merge csv and topo.json when topo.json changes, as this will create an infinite loop
- run merge as part of geo-to-topo Action, after new topo file is created
- remove redundant shell file
