firefox-esr and thundebird-esr broken by a typo

Hello.

FYI.

Using Poudriere with 2025Q3 tree, I get:
> [00:00:01] Warning: (mail/thunderbird-esr): Error: mail/thunderbird-esr depends on nonexistent origin 'LIB_DEPENDS+='; Please contact maintainer of the port to fix this.
> [00:00:01] Warning: (www/firefox-esr): Error: www/firefox-esr depends on nonexistent origin 'LIB_DEPENDS+='; Please contact maintainer of the port to fix this.
> [00:00:02] Error: Fatal errors encountered gathering ports metadata



The problem was introduced here:
