Comment (by SergeyBiryukov):

 In [changeset:"50772" 50772]:
 {{{
 #!CommitTicketReference repository="" revision="50772"
 Code Modernization: Bring consistency to preparing some fields on Network
 Settings screen:

 * `illegal_names`
 * `limited_email_domains`
 * `banned_email_domains`

 If any of these options have a falsey value, treat it as an empty string.
 This addresses a PHP 8.1+ deprecation notice when passing a `null` value
 to `str_replace()`.

 Additionally, avoid unnecessary type casting for better performance.

 Props hellofromTonya, jrf, SergeyBiryukov.
 See #51423.
