Typings incorrect for Axis Range min and max settings

[juliankigwana]

In ChartJs v3.5.1 the Axis Range Settings min and max are advertised as being numbers, when they actually accept both numbers and date strings. See tests:

Chart.js/test/specs/scale.time.tests.js

Line 130 in 957ca83

config.min = '2014-12-29T04:00:00';

Expected Behavior

The types to be defined as number | string;

Current Behavior

Project does not compile unless I had TS workarounds

Possible Solution

Steps to Reproduce

Context

Im trying to use a date string to set the min and max values in a scale.
