Upgrade Loki to 1.5

[Southclaws]

https://github.com/grafana/loki/releases/tag/v1.5.0

Be prepared for some configuration changes that may cause some bumps when upgrading,

Could be a rocky one. Will stage first before pushing to master.

Upgrade will require manual intervention to change the persisted files on disk to the correct user/group since the 1.5 container does not use root any more.

If using Pico's documentation default locations for persisted data:

chown -R 10001:10001 /data/targets/loki/*
