Removed unused lambda function

[jerrytfleung]

1. Removed unnecessary lambda functions (java, nodejs, python, ruby, go...) and directories to reduce the scope of vulnerability checks.
2. Updated codeQL to check the go code under collector directory.

Pull request overview

This PR significantly reduces repository scope by removing multiple language-specific layers, sample applications, and related CI/release infrastructure, while narrowing CodeQL scanning to the Go code under collector/.

Changes:

• Remove language-specific layer implementations, sample apps, and supporting tooling (Terraform/SAM/CloudFormation/scripts) across the repo.
• Update CodeQL workflow configuration to target only the collector directory.
• Update README/docs to remove/alter references to removed content.

This mentions using a CloudFormation template “here”, but the template file under utils/aws-cloudformation/ was deleted in this PR and there’s no replacement link. Please either restore/include the template (or equivalent instructions) or link to a new canonical location so users can actually set up the required OIDC/IAM resources.

Agree with this one too

Removed the cloudformation layer publish section as we used GHA to publish collector lambda layers

[Copilot]

The CodeQL job currently doesn't run github/codeql-action/analyze, so no results will be uploaded to code scanning. Also, the build step needs to run inside the collector directory (or set CodeQL source-root) since the repo root has no go.mod—otherwise Autobuild is likely to fail. Please add the Analyze step and ensure the build/source root is correctly set for the matrix directory.

Overall lgtm and makes sense if we don't build nor test with these.

I had one question and agree with Copilot recommendations.
