Fix Linter Errors

[C-Loftus]

• don't change any behavior or build tooling, just make sure the repo is in a better state for writing future tests
• make sure all err values are checked
• explicitly ignore or use all return values, don't allow just skipping them
• don't use deprecated methods
• fix ci/cd issue Test Nabu Subcommand Options action currently does not work #4
  • I am unclear why this wasn't an issue last time the docker image was made since it is an issue with the current main branch outside this PR.
• use proper format for variables in loggers
  • future clean ups for logging with be in other PRs
• set up ci/cd pipeline for linting
