[Bug] netlify.toml loadingStrategy is ignored

[gshel]

Bug Report

Describe the bug

When a user provides a netlify.toml file k/v pair: plugins.inputs.loadingStrategy: eager it is ignored and instead uses lazy for all img loading attributes.

Is this a regression?

This is not a regression.

Steps To Reproduce the error

1. Have a Netlify site with the Cloudinary integration enabled
2. Create a netlify.toml in the site's root dir
3. Add the following code:

   [[plugins]]
   package = "netlify-plugin-cloudinary"
   [plugins.inputs]
   loadingStrategy = "eager"

4. Add an image to the site's static resources
5. Refer to the added image in the src attribute of an html img tag
6. Save + commit + push all changes
7. Deploy site with latest changes
8. Go to site
9. Right click image and select Inspect to review attributes

Expected behaviour

When inspecting the img's attributes, I expect to see the loading attribute be eager since I specified it in my netlify.toml
