fixes #151

- What I did
Use the snyk/snyk:docker image instead of the snyk/snyk:alpine one

- How I did it
Change the SHA of the image in the vars.mk file
Add a e2e test which build a local image and try to scan this image with the containerized Snyk Provider

- How to verify it
e2e test should pass
On linux :

$ docker build -f ./e2e/testdata/Dockerfile -t local:build .

# when the image have been built 
$ docker scan local:build
...
Organization:      docker-desktop-test
Package manager:   apk
Project name:      docker-image|local
Docker image:      local:build
Platform:          linux/amd64
Licenses:          enabled

Tested 14 dependencies for known issues, found 15 issues.
