Django 2.2.11 fixes a security issue and a data loss bug in 2.2.10.

## CVE-2020-9402: Potential SQL injection via `tolerance` parameter in GIS functions and aggregates on Oracle

GIS functions and aggregates on Oracle were subject to SQL injection, using a suitably crafted `tolerance`.

## Correction de bogues

- Fixed a data loss possibility in the `select_for_update()`. When using related fields or parent link fields with Héritage multi-table in the `of` argument, the corresponding models were not locked (#31246).
