Update to use apiCheck as a function about angular-formly-templates-bootstrap

[benoror]

I'm willing to work on this chore, but I'm not sure how to proceed, as there's no updated docs regarding it. Would this be correct?:

Example: src/types/checkbox.js

export default ngModule => {
  ngModule.config(addCheckboxType);

  function addCheckboxType(formlyConfigProvider, formlyBootstrapApiCheck) {
    const c = formlyBootstrapApiCheck;
    formlyConfigProvider.setType({
      name: 'checkbox',
      template: require('./checkbox.html'),
      wrapper: ['bootstrapHasError'],
      apiCheck: function() {
        return: {
          templateOptions: c.shape({
            label: c.string
          })
        };
      },
      apiCheckInstance: c
    });
  }
};

Yes, totally forgot to update this. You almost have it. The only difference is you no longer need to specify that templateOptions is a shape because that is assumed. So it'd look more like this:

{
  apiCheck(check) {
    return {
      templateOptions: {label: check.string}
    };
  }
}

Good, gonna make a PR asap

Remember, this is built with es6 :-) So you could go crazy and do this:

apiCheck: check => ({templateOptions: {label: check.string}})

but that may be pushing it a bit ;-)

Note, this will technically be a breaking change because this new format isn't supported by older versions of angular-formly and we'll have to update the peerDep to be: >=6.20.0. Therefore, this will push angular-formly-templates-bootstrap to 6.0.0. Not bad, just wanna follow semver :-)

[kentcdodds]

Don't you worry about doing that for your PR though. I'll take care of that.

Released as 6.0.0! Thanks~
