languages.yml: don't assume .conf is Apache
languages.yml: don't assume .conf is Apache

The assumption that `.conf` files are Apache is causing many projects to
be detected incorrectly as being primarily "ApacheConf".

The `.conf` extension is widely used by software; Apache accounts for
only a very tiny proportion of its overall use. The addition of `.conf`
for ApacheConf has resulted in projects which contain none (or almost
no) Apache config being marked as primarily containing it.

The problem was introduced by 18a3ef9e5e80889d3daf88dab9338a65c97a7310
