As a PRU user, I want the feature flag removed for all other projects to be removed, so that the changes can be available on all wikis.
**Background:** Now that PRU is stable, the `$wgAllowRequiringEmailForResets` feature flag should be removed. After we have released on Wikivoyage & Wiktionary, then we should remove the feature flag on other wikis.
Currently, DefaultSettings.php reads:
```lang=php
/**
* Temporary feature flag that controls whether users will see a checkbox allowing them to
* require providing email during password resets.
*
* @deprecated This feature is under development, don't assume this flag's existence or function
* outside of MediaWiki.
*/
$wgAllowRequiringEmailForResets = false;
```
**Acceptance Criteria:**
* Remove feature flag for PRU changes for other projects (i.e., everything but Wikivoyage & Wiktionary)
