Follow-up to #33670.

Specifically, add a helper method to wrap loading in locales from blockly. This method will take care to detect whether or not blockly is actually loaded in the calling environment, and will give a helpful warning message if it isn't. Thanks @islemaster for prototyping the implementation!

Testing story

To recreate the original error from #33670, I added the following code:

diff --git a/apps/src/templates/projects/projectConstants.js b/apps/src/templates/projects/projectConstants.js
index 50a45e7ae49..90a040d986c 100644

 import PropTypes from 'prop-types';
+import i18n from '@cdo/locale';
+
+console.log(`i18n.projectTypeAlgebra(): ${i18n.projectTypeAlgebra()}`);
 
 export const projectDataPropType = PropTypes.shape({
   channel: PropTypes.string.isRequired,

Loading http://localhost.code.org:3000/educate/regional-partner/playbook then gives the following console output
