Add TypeScript Type about the injected kendoForm

[PekoPPT]

Describe the bug
The way the Kendo UI for Vue Native Form works is that it internally provides a kendoForm object that is later injected inside a FormContent.

The injection happens with a code like this:
const form = inject( 'kendoForm', {} );

but there is no TypeScript type that can be assigned to the injected object.

Expected behavior
Add a Type definition for the injected kendoForm object. The result would be something like:
const form = inject( 'kendoForm', {} ) as KendoFormInjectedProps
