Update dotnet new umbraco-extension template with newer @hey-api/openapi-ts (#19825)

* Updated hey-api as the client-fetch is bundled as part of @hey-api/openapi-ts in newer versions

* Regenerated a new package-lock.json file

* Fix typescript issue

* Update templates/UmbracoExtension/Client/package.json

Co-authored-by: Jacob Overgaard <752371+iOvergaard@users.noreply.github.com>

* Updated client dependencies

* Vite, TypeScript, hey-api
* Chalk & Cross-Env for the generate-client script

* Explicitly remove package-lock.json as it will be out of sync due to UMBRACO_VERSION_FROM_TEMPLATE

* Regenerated Hey API client that now ships client rather than dependancy

* Vite and Hey-API were already out of date (updated to the very latest)
