Translate object using lowest Z value with Python in Blender 2.8

Question

This question shows how to move the lowest vertex of a mesh on the grid, but the script given only works in versions before Blender 2.8: Translate object using lowest Z value python

Here is the script given:

import bpy

# get a reference to the active object
obj = bpy.context.object

# get the minimum z-value of all vertices after converting to global transform
lowest_pt = min([(obj.matrix_world * v.co).z for v in obj.data.vertices])

# transform the object
obj.location.z -= lowest_pt

What is the version of this script for Blender 2.8?

Note: I have intentionally copied a similar title so the users can find the Blender 2.8 version more easily.
