Changes proposed in this Pull Request:

Updates the ShippingLabelBanner class to only run add_meta_boxes action when on a shop_order page. I also updated the Jetpack connected function call as is_active() has be deprecated for quite some time and this meta box only gets shown if Jetpack is on the latest version.

Closes #35211 .

• This PR is a very minor change/addition and does not require testing instructions (if checked you can ignore/remove the next section).

How to test the changes in this Pull Request:

We should check if the banner still shows, it would look like this:

1. The easiest would be to load up a Jurassic site with a zip of this branch: pnpm --filter=woocommerce build:zip, unless you have a local version of WooCommerce setup with a connected Jetpack site.
2. Make sure your store is in the USA and the currency is USD, if you click the Personalize your store task you can add sample products (which will include shippable products)
3. Create an order with a shippable product (ex: Hoodie)
4. The banner should show up if you are on the edit order page and these criteria are met:

• Jetpack is up to date and you are connected (this includes the user being connected)
• None of the UPS, Fedex, ShippingEasy, or ShipStation shipping plugins are installed
• Your store is in the USA and the currency is USD
• WooCommerce Shipping is not installed or it is installed but the Terms of Service hasn't been accepted (probably easier to just not have it installed)

Other information:

• Have you added an explanation of what your changes do and why you'd like us to include them?
• Have you written new tests for your changes, as applicable?
• Have you created a changelog file for each project being changed, ie pnpm changelog add --filter=<project>?
