compile translation files to AST for efficiency

Overview:
Steps to Implement (See ui-plugin-find-user PR for example):

• Add @formatjs/cli as a dev-dep

  yarn add -D @formatjs/cli

• Add the following command to package.json with (replacing <ui-module-name> with your module name):

  "formatjs-compile": "formatjs compile-folder --ast --format simple ./translations/<ui-module-name> ./translations/<ui-module-name>/compiled"

• Run the command 

  yarn formatjs-compile

  If there are any errors, contact @Peter Murray to let him know of the error and he will work with Lokalise to get the files corrected. After Lokalise corrects files, update your branch from master.

• Modify .github/workflows/build-npm-*.yml to run formatjs-compile. In the env section near the top add:

  COMPILE_TRANSLATION_FILES: 'true'

  and after the "Run yarn test" step add a compile-translations step:

  - name: Run yarn formatjs-compile if: ${{ env.COMPILE_TRANSLATION_FILES == 'true' }} run: yarn formatjs-compile
