fix: Bump version to 1.0.4

Description:

• Bump version to 1.0.4
• I used the wrong command to upload to PyPI
• Added the following script to my .zshenv:

function publish_gear() {
  if [ "$PWD" != "/Users/brien/gnar/gear" ]; then
    >&2 echo "Must be on gear to publish"
    return
  fi
  GITHUB_BRANCH = eval "git rev-parse --abbrev-ref HEAD"
  if [ "$GITHUB_BRANCH" != "master" ]; then
    >&2 echo "Must be on master to publish"
  fi

  rm -rf build && rm -rf dist && python3 setup.py sdist bdist_wheel && twine upload -r pypi dist/*
}

• TODO: Publish via .gitlab-ci.yml
