Pipette+: App Should Correctly Display pipette images for new models

[Laura-Danielle]

overview

App should correctly display images for pipette+ models when they are attached to a robot.
The images used should be the same as the ones for the older models.

Show a generic multichannel image for attached multi-channel pipette+ and a generic single channel image for attached single channel pipette+

[Laura-Danielle]

We get this for free by keeping the naming conventions the same for pipette+.

Since the keyword single and multi remain in the string, there are no app changes needed.

After changing the name to p+<volume>_<type>_v2.0 this ticket is now relevant again.
