Cumulocity IoT software list uses incorrect type field

[reubenmiller]

Describe the bug

With the introduction of support for the Cumulocity IoT software type information, https://github.com/thin-edge/thin-edge.io/pull/2613, an error was spotted where the type property name was incorrectly specified in the ticket instead of softwareType as per the Cumulocity IoT specification

Using the wrong property name results in the type information not being displayed correctly in the Cumulocity IoT Device Management Application (on the device view).

To Reproduce

1. Start thin-edge.io
2. Inspect the device managed object in Cumulocity IoT, and see that the c8y_SoftwareList should contain an array of software items where type is used instead of the correct softwareType property.

Expected behavior

The software list should use the softwareType property

Environment (please complete the following information):

Property	Value
OS [incl. version]	Debian GNU/Linux 12 (bookworm)
Hardware [incl. revision]	Raspberry Pi 5 Model B Rev 1.0
System-Architecture	Linux rpi5-d83addab8e9f 6.1.0-rpi4-rpi-2712 #1 SMP PREEMPT Debian 1:6.1.54-1+rpt2 (2023-10-05) aarch64 GNU/Linux
thin-edge.io version	tedge 1.0.0-rc.2~255+g5088517

Additional context

[reubenmiller]

The software list sent to Cumulocity IoT now uses the softwareType property.

1. Install thin-edge.io
2. Check the software list (after the agent has started, you may need to refresh the Cumulocity IoT UI). Each software item should have a "type" visible in the UI

Here is an example (notice the badge next to each of the software item names):
