fix: separate domain based on plugin

[Soare-Robert-Daniel]

Closes #.

Summary

• Separated the translation domain for each sub-plugin and Otter Pro
• When the sub-plugin is bundled with Otter, their domains are changed to otter-blocks for JS and PHP files. (Their JS files have a check to load the translation based on their location -- in Otter or as an individual plugin).

Note

Unlike the PHP files, the JS have their translation tied up with their index.js path. You have to set the domain based on the script location.
