Might have repaired issue with Schema loading issues

Hi, I think this might help people with their issue with json loading as well as schema excessive wait issue when viewed by gtmetrix.

When browsing the contact form 7 files, I noticed ./includes/swv/swv.php has to call up https://json-schema.org/draft/2020-12/schema each time that it loads a form on a website, hence the feedback schema when doing a gtmetrix test.

When you insert that link into the browser it will automatically download the schema file. Once I had the file, I uploaded it to the main directory of my website to a folder called schema.

In order to do the edit of the swv.php file I had to disable the plugin and then I could edit. To fix with relative path issues, I did ‘./schema/schema’

After doing all this, I noticed the load times go from 2.5s down to 469ms which also reduced the fill time.

Hopefully this helps everyone out. I extremely like this plugin. I will do my best to help out the community.
