fix: compatible with latest dart version (#151)

* chore: `intl` package is not required, the API doesn't require `_dateFormatter`

* fix: ubuntu image

* chore: the pubspec.lock should not be in repo because it is determining libraries versions => different dart version in CI can't have different version of deps

* chore: `pub` ecosystem is no-longer in beta status

https://docs.github.com/en/code-security/dependabot/dependabot-version-updates/configuration-options-for-the-dependabot.yml-file#pub

* docs: update CHANGELOG.md

* chore: remove useless comment
