Revert "Deprecate query string auth tokens (#28390) (#28430)"
It shows warnings although the setting is not set, this will surely be
fixed later but there is no sense in spaming the users right now. This
revert can be discarded when another fix lands in v1.21.

2023/12/12 15:54:45 .../setting/security.go:166:loadSecurityFrom() [W] Enabling Query API Auth tokens is not recommended. DISABLE_QUERY_AUTH_TOKEN will default to true in gitea 1.23 and will be removed in gitea 1.24.

This reverts commit 0e3a5abb69.
