A4A > Marketplace: Fix WordPress.com hosting discount calculation

[yashwin]

Resolves https://github.com/Automattic/automattic-for-agencies-dev/issues/1751

Proposed Changes

This PR fixes the WordPress.com hosting discount calculation while using the Number Input component. It converts the value from the OnChange event to a number, as the previously provided value was a string.

Why are these changes being made?

• To fix the wrongly calculated discount for WordPress.com hosting.

Testing Instructions

• Open the A4A live link
• Go to Marketplace: Hosting > Go to Standard Agency Hosting tab > Click the + button on the Number Input and verify that the discount is as per the number of plans added, not the max discount. Also, verify the pointer on the slider is not at the right place(as per the no of plans), not at the end.
