🚑 Fix (AMP): incorrect usage of `data-ampdevmode` attribute on non-dev `<amp-script>` element

[chriskyfung]

Description

The data-ampdevmode attribute is being used on an <amp-script> tag in production code, which can lead to unintended behavior, such as:

• The custom script will not be executed.
• The AMP page will not be validated.
• The AMP page may not display correctly in some browsers.

Steps to Reproduce

1. Create an AMP page that includes the following code:

<amp-script src="https://example.com/script.js" data-ampdevmode></amp-script>

2. Publish the page and load it in a browser.

3. Inspect the network requests and observe that the script is being loaded from the development server instead of the production server.

Expected Behavior

The data-ampdevmode attribute should only be used in development environments and not in production. A script hash should be used to verify that the custom script and included in a meta[name=amp-script-src] element in the document head.

Actual Behavior

The amp-script does not run in production because the data-ampdevmode attribute is present.

Proposed Fix

Remove the data-ampdevmode attribute from the <amp-script> component in production environment.
