Fixed permission issue when mounting new data directory.

The commit of v5.2.1 commit 462dbb9b6b1288d8d6cb8af361ab9fb48e812cb6 Author: Adam Dullage adam@dullage.com Date: Sun Jul 7 14:29:47 2024 +0100

#213 - Set client file permissions in Dockerfile rather than entrypoint

made it so that containers started with empty directories fail with permission issue:

$ docker run -e "PUID=1000"   -e "PGID=1000"   -e "FLATNOTES_AUTH_TYPE=password"   -e "FLATNOTES_USERNAME=user"   -e "FLATNOTES_PASSWORD=changeMe!"   -e "FLATNOTES_SECRET_KEY=aLongRandomSeriesOfCharacters"   -v "datavol:/data"   -p "8080:8080"   dullage/flatnotes:v5.2.0
