chore(deps): updating examples/ deps to latest; tweak dependabot rules for examples

[trentm]

I'd prefer that at least the otel/edot-related packages are updating in a group.
They share a lot of transitive deps, so updating them in one reduces package-lock
churn.

This replaces a number of currently open dependabot PRs.

📝 Walkthrough

Walkthrough

This pull request modifies two files. The .github/dependabot.yml configuration changes the npm update schedule for the /examples directory from monthly to weekly intervals. It replaces the prior open-pull-requests-limit: 10 constraint with a new groups configuration containing an examples group that matches all dependencies. The examples/package.json file updates two dependencies: @opentelemetry/auto-instrumentations-node from ^0.69.0 to ^0.72.0 and @opentelemetry/sdk-node from ^0.211.0 to ^0.214.0.
