fix(regex): add missing 4th octet to email address IPv4 domain preset

Browse Source 
The 'Email address' preset in the Regular Expression operation was
missing the 4th IPv4 octet in the bracketed address form, causing
addresses like user@[1.2.3.4] to never match.

The IPv4 bracket group ended after {3} repetitions of 'octet.':
  \\[(?:(?:(octet))\.){3}\\]

This matches [1.2.3.] (a false positive) but not [1.2.3.4].

Fix: add the 4th octet group before the closing bracket, mirroring
the correct regex already used in ExtractEmailAddresses.mjs:
  \\[(?:(?:(octet))\.){3}(?:(octet))\\]

Closes #2150
