chore: split #8470 into smaller batches (batch 6)

[pearigee]

#8470 is to large for GitHub's API and Kokoro to handle. To get it over the finish line I am spitting it into smaller chunks. This is chunk 6, containing the following packages:

• google-cloud-edgecontainer
• google-cloud-gkerecommender
• google-cloud-gsuiteaddons
• google-cloud-ids

Code Review

This pull request updates several Google Cloud client libraries, including google-cloud-edgecontainer, google-cloud-gkerecommender, google-cloud-gsuiteaddons, and google-cloud-ids. The changes consist of removing snippet metadata references from the README files, updating contributing and license links to point to the repository root, and updating protobuf definitions to include new settings such as selectiveGapicGeneration, experimentalFeatures, and renamedServices. Additionally, widespread code formatting improvements have been applied across TypeScript source files, tests, and system tests, and the copyright year in webpack.config.js files has been corrected. There are no review comments to address, and I have no further feedback to provide.
