`patch-upstream.sh`

This script patches the git submodule folder `opentelemetry-lambda` with ADOT
recommended configuration. The upstream repo is vendor agnostic, but we modify
it slightly to create Lambda Layers that should help OpenTelemetry users trace
their Lambdas with Lambda Layers configured to export to the X-Ray backend.
