feat: optional description on subscription item

This very small patch allows for adding a custom item description to the subscription plans item list in the Subscription Doctype which is then copied over into the Sales Invoice for the given item. This is useful for specifying individual parameters or assignments for subscription line items.

Subscription Plan Detail Table (Plans field on Subscription Doctype):

Sales Invoice Item Table (Items field on the Sales Invoice Doctype):

I'd be glad to put more work in on this (tests, docs, refactoring) if it's an acceptable feature. Otherwise, I'll maintain it out of tree. Any comments?
