I found this solution and initially was unable to get it to run. As @egodigitus mentions, you may need to run the following command after parted.
$ sudo pvresize /dev/sda3
I have updated the gist to now include the pvresize portion, thank you +1
Hello, i think "sudo pvresize /dev/sda3" should be executed, as @Adrian016 wrote, after "sudo parted". At least only fixed order made effect. Since physical volume contains logical groups and those contains logical volumes.

Wow. Saved my bacon after setting up a Ubuntu VM on Proxmox and forgetting to set partitions properly. Kept building complexity in the Ubuntu VM until I ran into the disk size wall. Saved me hours of work!
