update/fix default values in config file and remove outdated information

[agowa]

The configuration file currently contains some "alternative" or better outdated information.

E.g. it still mentions the defunct and for sell netdb.i2p2.no endpoint as a reseed.
Having non-default values listed as "default" within the config is also confusing to users, as it can easily make them waste hours on troubleshooting.

Stated defaults in config file:

[reseed]
## Default: "mainline" I2P Network reseeds
# urls = https://reseed.i2p-projekt.de/,https://i2p.mooo.com/netDb/,https://netdb.i2p2.no/

actual defaults:

i2pd/libi2pd/Config.cpp

Lines 212 to 225 in 26463c5

	("reseed.urls", value<std::string>()->default_value(
	"https://reseed2.i2p.net/,"
	"https://reseed.diva.exchange/,"

Config does not say that # urls are default values.
I agree however that example should show active services.

Well I'd say it does, as it is literally following the Default: "mainline" I2P Network reseeds line. But even if you say this doesn't count for some reason. It still heavily implies being the default as that file almost exclusively lists the default values for everything else.

Edit: Is it possible to just auto generate that config file from the above cpp file? It looks like almost all of the descriptions are within it already and that would ensure that the config file (as shipped) always is in sync with the code.
