1. Update google-ads-node in package.json
    1.1 Update badge version in readme.md + container.jsx
    2. yarn && yarn build
    3. update scripts/schema.json (https://googleads.googleapis.com/$discovery/rest?version=v2)
    4. update compiled_resources.json by running `pbjs -t json googleapis/google/rpc/*.proto googleapis/google/longrunning/*.proto googleapis//google/ads/googleads/v2/common/*.proto googleapis//google/ads/googleads/v2/errors/*.proto googleapis//google/ads/googleads/v2/enums/*.proto googleapis//google/ads/googleads/v2/resources/*.proto googleapis//google/ads/googleads/v2/services/*.proto > compiled_resources.json`
