• Add buf config ls-modules command to list configured modules.
• Fix issue where buf generate would succeed on missing insertion points and panic on empty insertion point files.
• Update buf generate to allow the use of Editions syntax when doing local code generation by proxying to a protoc binary (for languages where code gen is implemented inside of protoc instead of in a plugin: Java, C++, Python, etc).
• Allow use of an array of strings for the protoc_path property of for buf.gen.yaml, where the first array element is the actual path and other array elements are extra arguments that are passed to protoc each time it is invoked.
