fix: removed not supported static image (#186)

#197

`seldonio/egine` image was removed from the project: SeldonIO/seldon-core@6fc7f9b

There is no need to keep this image in static list of image retrieval script.

Summary of changes:
- Removed seldonio/egine image from the static list (and the whole static list, because it is empty now).
