Improved Embed Translation in Translator Plugin

This pull request introduces improvements to the Translator plugin by adding comprehensive translation support for embeds within Discord messages. Now, titles, descriptions, fields, and footers in embeds can be translated, enhancing the plugin's utility and user experience.

Enhancements:

• Embed Content Translation: Titles, descriptions, fields, and footers within embeds are now fully translatable.

Showcase

Change is tested on multiple embeds in single message, together with content of messages itself.
