PR Summary

• Improved Internationalization Across the App
  This PR carries out quite a few changes that revolve around replacing hardcoded strings within the application with their translated versions. The benefits of this are twofold; firstly, it makes the application more accessible to non-English speaking users, and secondly, it facilitates easy translation into any language. Changes were made in the following areas:

• In the Profile Controller, a hardcoded string was replaced with a translated version.

• The language resource files were enriched with several additions, including messages to denote success during API key creation, error messages, button labels, and column header labels among others.

• For Personal Access Tokens interface, hardcoded strings such as "Create New Token" and "Delete" were swapped for their translated counterparts.

• New sections were added to display translated messages which alert users when a new personal access token (a key that authorizes API calls) is created.

All these changes help to make the application much friendlier for international users and simpler to localize in the future.
