Original shiori is actively maintained again

[dav-m85]

Just posting here in case it hasn't been noticed, but go-shiori/shiori is actively maintained again by its community on the original repository since RadhiFadlillah left.

This fork's README could be improved by changing this section:

Sadly the original maintainer of Shiori is no longer able to maintain the project anymore. This project was forked during a prior hiatus and changes with the original project means this project couldn't be merged back.

... for something explaning more precisely why this fork is still maintained in parallel. Cheers !
