Fix text e-mails for review replies.
Review Request #14111 — Created Aug. 19, 2024 and submitted — Latest diff uploaded
The template for text e-mails for review replies was inadvertantly
including the.htmlversion of the content template instead of.txt.
This was causing the message to send HTML code, but marked as plain
text.
Loaded the preview-email page and saw that before the fix it showed HTML
code and after it showed the expected text content.
