Installation/Upgrading script is user dependent

Steps to reproduce

1. Run the script first time with a user, lets say marcel@instance.url
2. Try to run the script to upgrade the software with another user, lets say root@instance.url. You'll get this error

# sudo sh -c "$(curl -sSL https://get.funkwhale.audio/upgrade.sh)"

[Beginning upgrade]
[1/4] Retrieving currently installed version from /srv/funkwhale/ansible/playbook.yml
[1/4] No target version specified, retrieving latest version from https://docs.funkwhale.audio/latest.txt

Upgrade summary:

- Current version: 1.1
- Target version: 1.1
- Upgrading may cause temporary downtime on your pod

Do you want to proceed with the upgrade? [YES/no]: 
[2/4] Replacing current version number in /srv/funkwhale/ansible/playbook.yml…
[3/4] Upgrading ansible dependencies...
[3/4] Upgrading Funkwhale using ansible playbook in /srv/funkwhale/ansible...
sh: 98: /root/.local/bin/ansible-galaxy: not found

What happens?

Seems that this happens because the installation of dependencies is made with a per-user basis, so running the script with other users will not find out the dependencies.

Workaround

Maybe running the script with other users but from the first user's /home directory could work.

What is expected?

I expected that the dependencies are not user dependent, so the script can be run with any other user too.
