chore: Add independent service directories to .gitignore

Add the following services to .gitignore as they are managed
as independent git repositories:
- services/sapiens-mobile/
- services/sapiens-web/
- services/sapiens-web2/
- services/sapiens-web3/
- services/sapiens-stock/
- yakenator-app/

These services have their own git histories and will be managed
separately from the main site11 repository.
