Import of old releases into ATR

Hello all,

As some of you might have noticed, Apache Trusted Releases has
retroactively created releases for all the files in archive.apache.org,
using a modified version of the heuristic from projects.apache.org:

https://release-catalog-test.apache.org/logging/index.html

Since the heuristic is based on keywords and "log4j" appears often, some
artifacts are misclassified (e.g., Log4j Scala releases are classified
as Log4j).

I reached out to Tooling to get database dumps (as CSV files) for the
part related to Logging Services, and I've corrected them here:

https://gist.github.com/ppkarwasz/27dd55b79bde688cb5d83563c305febf

The gist includes a changes.md explaining what was modified and why. All
the files in the following folder should have been classified:

incubator/{flume,log4cxx,log4net,log4php}
jakarta/log4j
flume/
logging/

Could you review these files before I send them back to Tooling?

One outstanding question:
- When were the Log4net 1.x and 2.x final releases retired: at the same
time as the first release of the next series, or shortly after?
