Bug description

Setting the theming option with

occ theming:config disable-user-theming 1 (same with on, true, yes, etc.)

results in a string type in Database:

+---------+----------------------+-------------+------+------+
| appid   | configkey            | configvalue | type | lazy |
+---------+----------------------+-------------+------+------+
| theming | disable-user-theming | 1           |    4 |    0 |
+---------+----------------------+-------------+------+------+

which will fail on next Request with Exception "message":"conflict with value type from database" in nextcloud.log giving an Internal Server Error in Browser.

Reason seems, that function function getValueBool in lib/private/AppConfig.php expects type 32 in Database. Unfortunately the command occ theming:config lacks an option to explicitly set type bool.

Steps to reproduce

1. Fresh install
2. Set option `disable-user-theming' to true (or false or anything else) using command occ

Expected behavior

Same as having set the option via UI, which results in database entry

+---------+----------------------+-------------+------+------+
| appid   | configkey            | configvalue | type | lazy |
+---------+----------------------+-------------+------+------+
| theming | disable-user-theming | 1           |   32 |    0 |
+---------+----------------------+-------------+------+------+
