fix(carddav): Make system contact phone number RFC compliant

[GretaD]

• Resolves: "OTHER phone" vs "Other email" contacts#3403

Summary

The RFC specs the allowed types for a TEL property:

server/apps/dav/lib/CardDAV/Converter.php

Line 92 in 1f2a9de

$vCard->add(new Text($vCard, 'TEL', $property->getValue(), ['TYPE' => 'OTHER', 'X-NC-SCOPE' => $scope]));

. OTHER is invalid. This was a bad copy-paste from another prop.

Checklist

Works but commit and PR title are really misleading

change it to fix(carddav): Make system contact phone number RFC compliant

We are not fixing the capitalization here. We are fixing an invalid TEL property in the system contact vcard.
