I had a weird `ds-example` service running as well as onlyoffice

Describe the bug

OnlyOffice was conflicting with invidious over port 3000, same as this other user report.

After investigating, I have a few ds processes:

# systemctl list-unit-files |grep ds-
ds-converter.service                                                          enabled         enabled
ds-docservice.service                                                         enabled         enabled
ds-example.service                                                            enabled        enabled
ds-metrics.service                                                            enabled         enabled

And the ds-example service was running on port 3000.

# ls -l /var/www/onlyoffice/
total 0
drwxr-x---  2 ds ds   6 31 août  09:57 Data/
dr-xr-x--- 12 ds ds 213 31 août  09:57 documentserver/
dr-xr-x---  4 ds ds  50 31 août  09:57 documentserver-example/

Is this "example" a leftover from some other configuration? I disabled the ds-example service and everything works.

Context

• Hardware: bare metal x86_64
• YunoHost version: 11.2.4
• I have access to my server: full
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: 7.3.3~ynh1

Steps to reproduce

• systemctl status ds-example.service
• curl 127.0.0.1:3000

Expected behavior

This service should not be running. Moreover, this documentserver-example folder should not exist.
