This commit adds "read-all" permissions to golangci-lint, codecov, and sonarqube workflow files. This change ensures that all necessary activities are allowed during the workflow processes.
A codecov.yml configuration file has been added to specify the coverage target and other codecov settings. The CI pipeline has also been streamlined to directly generate the coverage profile without using grep for filtering ignored code paths. This makes it easier to understand and maintain the testing and coverage reporting process.
The codecov workflow in the CI pipeline has been adjusted to produce more accurate coverage profiles. Previously covered but now-ignored code has been removed from the coverage profile by filtering out desired patterns with 'grep'.
Added a new workflow in '.github/workflows/codecov.yml' that runs on all three OS: Ubuntu, MacOS, and Windows with '1.22' version of Go. This workflow performs a test coverage check and then uploads the coverage data to Codecov. The workflow is activated on every 'push' or 'pull request' to the 'main' branch.
