ci: add semantic release

[dubisdev]

We can use semantic release GH action to analyze commits and automate releases and changelogs.

Roadmap

I will update it with PRs.

• Get version from app.getVersion() and add it to process.env.CEREBRO_VERSION. By doing this, we dont depend on the package.json for getting the version and we can set it dinamically in CI with the result of the semantic-release.
  • Change version core plugin to get the version from process.env.CEREBRO_VERSION.
  • docs: update developers API so they know this new env variable is available.
  • chore: add cerebro version to process.env #585
• Add linter to commits so we ensure they follow conventional-commit specification.
  • Add commitizen --> cli tool for writting conventional commits
  • Add husky and commitlint to lint commits by using git hooks.
  • chore: implement conventional commit standard #586
• Add semantic-release step to GH actions
  • Move build step to new GH action, triggered by new releases.
    • Get the release version
    • Set it in CI by using the electron-builder cli options
      Should work with electron-builder -c.extraMetadata.version={{ semantic-release output version }}
    • Build the executables
