contrib.gis.geoip does not support Country-Lite version from DBIP

[Nathan Humphreys]

The

db_type

property of the geoip database metadata for the dbip (​https://db-ip.com/db/lite.php) lite databases is being returned as "DBIP-Country-Lite"

The check here then fails

​https://github.com/django/django/blob/stable/3.2.x/django/contrib/gis/geoip2/base.py#L107

despite the database being in the mmdb format.

I believe Django should support the (free) dbip lite databases as well as the commercial maxmind databases.

Changing the above line to check for

if db_type.contains("Country"):
    ...

would be sufficient. As would a second check to check for

 if db_type.endswith("Country") or db_type.endswith("Country-Lite"):
    ...

A similar change would be required the the dbip City-Lite database to be supported.

I am happy to put in a pull request but I am also hoping we can find a way to get this into the 3.2.x branch as well as a future 4.x release if thats possible.

A patch is welcome. Unfortunately, per Django release policy, this will not enter 3.2.x, nor 4.0.x, as it's not a regression.
