• remove package-lock.json from .gitignore
• delete .npmrc and .yarnrc

  • remove travis/codecov badges
  • add actions badge instead (replace REPO NAME HERE ;): [![Build Status](https://github.com/semantic-release/[REPO NAME HERE]/workflows/Test/badge.svg)](https://github.com/semantic-release/[REPO NAME HERE]/actions?query=workflow%3ATest+branch%3Amaster)
• create package-json.lock
• add to package.json:

  • test:ci script which doesn't run lint pre script

  • renovate config

       "renovate": {
         "extends": [
           "github>semantic-release/.github"
         ]
       }
    

• update branch protection: remove required status by Travis and Codecov, add required status for "test" (wait for first build of PR)
