feat: loads v2 models
- Deploys models from the new location in addition to the existing one.
- If wiki appears in the following url, the new model will be deployed. Otherwise, we keep using the existing wiki.txt in the one-off location:
https://analytics.wikimedia.org/published/wmf-ml-models/addalink/v2/wikis.txt
- I've added tiwiki and pwnwiki to the v2/wikis.txt for testing. I'll add rest of the new wikis once they are deployed successfully.
