chore: Improve translation service with HTML and plain text support (#11305)
# Pull Request Template

## Description

This PR changes to translation to properly handle different content
types during translation.

### Changes

1. **Email translation with HTML support**
   - Properly detects and preserves HTML content from emails
   - Sets `mime_type` to 'text/html' when HTML content is present

2. **Email translation with plain text support**
   - Falls back to email text content when HTML is not available
- Sets `mime_type` to 'text/plain' when HTML is not available and
content type includes 'text/plain'

3. **Plain message with plain text support (Non email channels)**
   - Sets `mime_type` to 'text/plain' for non-email channels
- Fixes an issue where Markdown formatting was being lost due to
incorrect `mime_type`
   
**Note**: Translation for very long emails is not currently supported.
