Update the regex_findall example (#43052)

Browse source 
<!--- Your description here -->
The example has:
`{{ 'Some DNS servers are 8.8.8.8 and 8.8.4.4' | regex_findall('\b(?:[0-9]{1,3}\.){3}[0-9]{1,3}\b') }}`

It needs be double backslashes to escape the backslashes:
`{{ 'Some DNS servers are 8.8.8.8 and 8.8.4.4' | regex_findall('\\b(?:[0-9]{1,3}\\.){3}[0-9]{1,3}\\b') }}`
