maint(ct): rename periphery deploy config folder (#10793)

Renames the folder periphery-deploy-config to
deploy-config-periphery and reorganizes its contents so that it's
a little bit cleaner. Means that the folder will appear next to
the other deploy-config folder and will be easier to find and read.
