DB + SNCB: skip all E2E tests after endpoints permanently shut down

[KristjanESPERANTO]

I would like to reduce the number of failed tests. As a start, I suggest first deactivate the tests for both profiles - DB and SNCB.

Currently, 201 E2E tests are failing. After this change, there will be 25 fewer. I would look at the rest step by step.

Since the endpoints will most likely not return, we could alternatively remove them completely.

I haven't looked into it closely, but hafas.bene-systems.com (cf #41) could actually be a viable replacement for some of that.

Thanks for the hint! I looked into hafas.bene-system.com. The mgate.exe API exists but requires authentication:

curl -s -X POST "https://hafas.bene-system.com/bin/mgate.exe" \
  -H "Content-Type: application/json" \
  -d '{"ver":"1.52","lang":"eng","auth":{"type":"AID","aid":"test"},"client":{"type":"AND"},"svcReqL":[{"meth":"ServerInfo","req":{}}]}' | jq '.err, .errTxt'
# Output: "AUTH", "HCI Core: Authorization fail"

I think that until we resolve this, the SNBC tests should be disabled.
