Rename component.json.erb to bower.json.erb

"In versions of Bower before 0.9.0 the package metadata file was called component.json rather than bower.json. This has changed to avoid a name clash with another tool. You can still use component.json for now but it is deprecated and the automatic fallback is likely to be removed in an upcoming release."
Create bower.json instead of componenet.json
