Update Documentation (both in swagger and RST) to make it really clear how to use the query parameter based id for blobs.

[MikeNeilson]

I also mentioned to @MikeNeilson that i'm not sure why we have to use /blobs/ignored?blob-id instead of just /blobs?blob-id and catch when blob-id is provided to the getAll method? Might be a limitation of Javalin?

Ok I totally missed this. It does work if you have /blobs/ignored?blob-id. Someone can close this, but I would argue it's not the most intuitive for a user.

Instructions for blobs with / in the name require additional clarity.
