URL of dbparser XML blog

[alizat]

Currently the URL of the XML blog is:
https://dainanahan.github.io/1/01/journey-to-the-center-of-the-drugbank-xml-database/

It should look something like this:
https://dainanahan.github.io/2019/01/journey-to-the-center-of-the-drugbank-xml-database/

... to be like the link to our other blog:
https://dainanahan.github.io/2019/02/drug-bank-browser/

BONUS:
Once fixed, redirect any calls to the old link(s) to the new one.
