Add Operator docker image build utilities

[jj22ee]

Issue #, if available:
Add Docker file to provide build of ADOT JS in a docker image, similarly to how OTel does it for NodeJS:
https://github.com/open-telemetry/opentelemetry-operator/tree/main/autoinstrumentation/nodejs

Description of changes:

• Add autoinstrumentation.ts file to mimic upstream's autoinstrumentation.ts, but also point to our ADOT JS instrumentation.
• Add Docker file to build docker image similarly to upstream's Docker file, but uses scratch image and the source code from this GitHub repository (since the package is not available in NPM).
• Add package.json specifically for the docker image build to mimic upstreams package.json that is also specific for their docker image build. Most of the dependencies (ADOT JS's dependencies) can be removed once ADOT JS is uploaded to NPM. After that, we can just have a singular dependency on ADOT JS from NPM.
