[Site Bug] Issue with the page: /self-hosted/latest/upgrades/upgrade-docker/

[Miotis]

Describe the bug

Inconsistency between the Image and Volume path caused incorrect image creation without persistence at all.
The main page https://docs.timescale.com/self-hosted/latest/install/installation-docker/ describes that the mounting point for timescaledb-ha is /home/postgres/pgdata/data.
Therefore this page: Upgrading TimescaleDB within Docker wasn't fully updated and both step 3 code snippets contained the wrong mounting points for timescaledb-ha image. It should be updated to /home/postgres/pgdata/data instead of /var/lib/postgresql/data

Page affected
