swagger-codegen README.md section "Modifying the client library format" references old location for templates

Description

I found it really hard to find the handlebars templates, as the README.md referenced the location for swagger-codegen 2.4.7:
https://github.com/swagger-api/swagger-codegen/tree/v3.0.10#modifying-the-client-library-format
"You can look at modules/swagger-codegen/src/main/resources/${your-language} for examples."
