Suppress auto-update message

can be done by setting a flag in a very specific configuration file.

## Filte
`\DBeaverData\workspace6.metadata.plugins\org.eclipse.core.runtime.settings\org.jkiss.dbeaver.core.prefs`

## Setting
`ui.auto.update.check=false`

## How to
``` bash
echo "variable.name=value" >> ~/.local/share/DBeaverData/workspace6/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.jkiss.dbeaver.core.prefs
```

```bash
sed -i 's/^variable.name=.*/variable.name=newvalue/' ~/.local/share/DBeaverData/workspace6/.metadata/.plugins/org.eclipse.core.runtime/.settings/org.jkiss.dbeaver.core.prefs
```

Start by reviewing how the Flatpak handles DBeaver's workspace preferences, especially the org.jkiss.dbeaver.core.prefs file under workspace6/.metadata/.plugins/org.eclipse.core.runtime/.settings. Verify whether ui.auto.update.check=false can be applied reliably, then confirm that the auto-update message is suppressed without breaking the workspace configuration.
