Unchecked use of FS_CHMOD_FILE constand (PHP8.1 compatibility?)

Hello. Bookly failes in the Booking process after the address input step (more specifically: when generating the .ics attachment) with this error:
`wp-fpm-1 | NOTICE: PHP message: PHP Fatal error: Uncaught Error: Undefined constant “FS_CHMOD_FILE” in /var/www/html/wp-admin/includes/class-wp-filesystem-direct.php:164

Looks like Bookly is assuming a constant is defined instead of checking. Funny enough, this just happens with PHP8.1, not with 7.x versions.

Here is a good explaination for what I think is happening:

Thanks for looking into this!
