[feature] Use the 'restock' column to display css/xpath include filters when in changedetection mode

[Corb3t]

Version and OS
v0.49.0 on Unraid 7.0

Is your feature request related to a problem? Please describe.
I love the Re-stock and price detection feature within Change Detection, but I would love if it displayed the inventory available, if it can, and notify if the inventory value changes. You could also setup notifications for specific inventory values - ex: "Only 5 left"

Describe the solution you'd like
When a page is marked as a re-stock/price detection item, it will attempt to find the inventory and display it the "Re-stock & Price" column next to the "In Stock" tag.

Describe the use-case and give concrete real-world examples

Example 1 - HighSpy.io:

Example 2 - Haskells:
