fix missing backslash in documentation #17283
fixes issue #17208
Summary of the issue:
Problem:
The sentence originally read: "Normal backslashes in the Replacement field should thus be doubled, e.g., "a\b" should be typed to get the "a\b" replacement."
In the HTML output, this rendered incorrectly as only one backslash (a\b), when two backslashes (a\b) were intended.
Solution:
The sentence was updated to correctly show double backslashes where needed: "Normal backslashes in the Replacement field should thus be doubled, e.g., "a\\b" should be typed to get the "a\b" replacement and "a\b"
should be typed to get the "a\b" replacement.
This ensures that two backslashes are correctly represented in both Markdown and HTML output
