Ignore files when `amplify push`, specifically lambda function files. Example: Add .amplifyignore to not send some .ts (typescript) files to AWS.

Start by tracing the Amplify CLI Lambda packaging path used by `amplify push`, focusing on how TypeScript files are selected for upload. Done means a configured ignore rule can exclude specified `.ts` files from Lambda deployment without preventing the remaining function files from being pushed.
