Add GeoIP commercial databases

Hello

Is your feature request related to a problem? Please describe.
The documentation is not clear if we can you GeoIP commercial database (other than GeoIP enterprise database). Today I have subscription for GeoIP2-Country, GeoIP2-ISP and GeoIP2-Anonymous, I wanted to use at least GeoIP2-Country but didn't work.
It seems that geoip processor only works with Geo2Lite.

I have the following configuration:

extensions:
  geoip_service:
    maxmind:
      databases:
        country: "/usr/share/GeoIP/GeoIP2-Country.mmdb"
      database_refresh_interval: PT1H

In case you can access database samples here: https://github.com/maxmind/MaxMind-DB/tree/main/test-data

Describe the solution you'd like
Have the possible to use GeoIP2 database with configuration like:

extensions:
  geoip_service:
    maxmind:
      databases:
        geoip2-country: "/usr/share/GeoIP/GeoIP2-Country.mmdb"
        geoip2-isp: "/usr/share/GeoIP/GeoIP2-ISP.mmdb"
      database_refresh_interval: PT1H

Describe alternatives you've considered (Optional)
Or similar to what it's done in logstash, determine the database in the processor like:

  processor:
    - geoip:
        entries:
          - source: "/clientIp"
        database: "/usr/share/GeoIP/GeoIP2-Country.mmdb"

Additional context
It's seems to don't work ever when providing GeoLite2-Country.mmdb by localpath directly.

data-prepper-config.yaml:

extensions:
  geoip_service:
    maxmind:
      databases:
        country: "/usr/share/GeoIP/GeoLite2-Country.mmdb"
      database_refresh_interval: PT1H

pipeline.yaml:

version: "2"
test-pipeline:
  source:
    http:
  processor:
    - parse_json:
        source: "message"
    - geoip:
        entries:
          - source: "/clientIp"
  sink:
    - stdout:

input data sample:

{"clientIP":"185.126.231.50"}

Start with the geoip_service MaxMind configuration and geoip processor shown in the issue; compare the requested commercial database names with the existing country configuration. Reproduce the pipeline using the supplied GeoLite2-Country.mmdb or MaxMind test data, then consider the issue done when the configured GeoIP2 databases load and the processor enriches the sample event.
