Disable long line checks in syntax check

[warpr]

Problem

Sometimes it useful to reference documentation in code comments, for example when documenting the contents of fields provided by a third-party API or integration. This can look like:

// - slot_start_sec: Start time of the appointment slot in seconds of UTC time since Unix epoch.
// https://developers.google.com/maps-booking/verticals/local-services/reference/rest-api-v3/bookings/slot-specification
$start = new DateTime('@' . $booking->slot_start_sec);

Currently the syntax checker doesn't allow long lines like this, and there is no way to
disable the check for just this line.

Solution

Just disable the max line length check -- we don't need it for most files, as most existing files and all new files are processed with prettier, which will take care of the long line formatting where possible.
