[Enhancement] Improve "Create New Product" Process Descriptions

[PowerChell]

1. Clarify the Product ID is what shows up in the URL

• When in the "Create New Product" process, it would be nice to clarify that under "Product ID", this is what will show up in the URL.
• Suggested update: The unique identifier for your product that will appear in the URL (e.g., source.coop/your-account/product-id). ⚠️ Important: Once set, the Product ID cannot be changed. Choose carefully.

2. Improve description of "Create New Product"

• It would also be nice to enhance the description of the "Create New Product" to state how all of the components of the product can be updated later on except for the Product ID.
• Suggested update: Create a new product to share with others on Source Cooperative. All product details can be updated after creation except for the Product ID.
