Update guidance on form template location. They don't necessarily have to be placed in /app/templates and will work in the theme directory too. The current text also seems to suggest that they can be placed in the core directory - something which I don't believe should be advised,
- Stronger wording around "use composer"
- Consistent domain and email address naming
- Removed example for publishing non-composer modules (those shouldn't be encouraged)
- Removed instructions for installing modules from archives
