Add storage_display_name option to StorageConfig on komorebi-bar storage widget

[1337cookie]

This PR adds a storage_display_name to the komorebi-bar storage widget config with options for Mount, Name, MountAndName and NameAndMount.

By default it will be Mount eg. "C:" which is the same as the old behavior. Using Name will give the label the disk was given. NameAndMount and MountAndName will combine the two.

Unnamed disks will have no value when using Name but would usually appear as "Local Disk" in windows explorer for example.

"Storage": {
    "enable": true,
    "storage_display_name": "Name",
    "label_prefix": "IconAndText"
}
