obsolete IMGUR as image hoster

[mi-hol]

@mck1117 @chuckwagoncomputing would you perhaps have the images required to complete the ToDos?

ToDo:

1. add correct polarity scope image
2. add wrong polarity scope image

@chuckwagoncomputing as I fail to see the root cause of lint error, would you perhaps see it?

Run bash ./wiki-tools/lint.sh
In ./Trigger-Configuration-Guide.md:
Images/trigger_VR_sensor_correct_polarity
     [1](https://github.com/rusefi/rusefi_documentation/actions/runs/4472185202/jobs/7858172465#step:4:1)   ./Images/trigger_VR_sensor_correct_polarity.png
In ./Trigger-Configuration-Guide.md:
