Document latest template files.

[technophile-04]

Description:

We have documenting stuff at TEMPLATING-FILES.md with examples to corresponding .args.mjs lets add #131, #138 , #129 .

Also #138 we don't actually have any examples (might update eip-5792 example with it) but I think we are gonna hit similar situation in future where we add things to template.mjs and don't have corresponding example of .args.mjs (it might live in 3rd party extension).

What if we create a fake extension which uses all the .args.mjs and all the fields in init. and all the example args.mjs file point to it. So whenever we add .template.mjs file we also add corresponding .args.mjs in that fake extension. This will also help test the PR which adds the template.mjs file.

💯 Love this idea.
