Harmonize category names across projects

[Daniel-Mietchen]

On Commons, we have
https://commons.wikimedia.org/wiki/Category:Uploaded_with_reCitation_Bot ,
which has led to
https://en.wikisource.org/wiki/Category:Uploaded_with_reCitation_Bot
for equations and tables,
albeit we are using
https://en.wikisource.org/wiki/Category:Uploaded_by_Recitation-bot
to track uploads on Wikisource.

This means we have differences in capitalization, "by" vs. "with" and "_" vs. "-". That needs to be more coherent.

One dirty secret is that right now I am using the commons template https://github.com/wpoa/recitation-bot/blob/master/recitation-bot/commons_template.py#L121 for both Commons and Wikisource uploads. We can customize the template by site - not an issue. But for consistency I think it'd be great if we can just stick to one.
I actually don't know where Uploaded_by_Recitation-bot string is coming from. Do you know what's producing it?
