[pve-devel] [PATCH manager] ui: lxc: resources: add Detach text for mountpoints

[Aaron Lauterer <a.lauterer@proxmox.com>]

Instead of showing 'Remove' for a mountpoint, change the text to
'Detach' and only show 'Remove' for unused volumes.

This aligns the behaviour with VMs and will make it clear, that a
mountpoint first needs to be detached before it can be fully removed.

I took the code from the qemu/HardwareView.js and only made minor
changes to the check if it is a used disk/volume.
Since it is only a minor change, I did not go all the way to modernize
it and also stayed with `var ...` instead of `let ...` when defining the
`isUsedDisk` variable for consistency.
