all: Fix various bugs related to resource type names that match the provider type name (i.e. no resource type suffix)

[austinvalle]

Closes #419

This PR fixes three bugs, two of which were related to resource type names that have no type name and are equal to the provider name itself, which is valid. (Example: http data source from the terraform-provider-http provider)

1. In the validate command, resource types that had no type name would return a validation error for file mismatching
2. In the generate command, resource types that had no type name would take priority over other files present, introduced in Allowing single word resources to use templates #147. I believe this was likely caused because we didn't have any providers that had multiple resources alongside a resource with a type name the same as the provider 🙃

The third bug was just related to static file copying from templates:

3. In the generate command, static files which we wish to not overwrite in the destination should not cause the docs generator to throw an error.

Notes

• This PR also removes the .vscode folder at the root of this project, since we don't typically include IDE files in repositories
