ci: disable docker

[fmorency]

This pull request modifies the .circleci/config.yml file to deprecate the use of the Docker job and related steps while updating the Go module cache handling. The changes streamline the CI configuration by focusing on Go-related tasks and removing Docker-related functionality.

Deprecation of Docker-related functionality:

• Commented out the docker orb and all associated steps, including building, pushing, and tagging Docker images, as well as storing Docker-related artifacts. This includes the removal of the docker job from workflows and its branch filters. [1] [2] [3]

Updates to Go module cache handling:

• Replaced go/load-cache and go/save-cache steps with go/load-mod-cache and go/save-mod-cache to align with updated Go module caching practices.

.circleci/config.yml:21

• Verify that circleci/[email protected] supports the go/load-mod-cache and go/save-mod-cache steps; if not, upgrade the orb or revert to the cache step names your current orb supports to avoid CI failures.

.circleci/config.yml:28

• The files parameter for codecov/upload expects a YAML sequence. For a single file, use files: ['/tmp/manifest-node-exporter-coverage/coverage-merged.out'] or switch back to file: if the orb version requires it.

-          files: /tmp/manifest-node-exporter-coverage/coverage-merged.out

• [nitpick] Since Docker support is deprecated here, consider removing these commented-out lines entirely to clean up the CI config instead of leaving them in place.
