New owner and release schedule

[GideonBear]

I'm happy to announce Topgrade v16.1.0, and with it, a faster release schedule! Releases have been fully automated, and will be made immediately after major fixes.
On another note, I'm joining Topgrade as co-owner and primary maintainer. Thanks @SteveLauC for all your work on Topgrade!
