build(tgbot-gen): Changes and additions required to generate the API client with auth (cookie)

I use a standard set of templates, changes are made in api-header.mustache and api-source.mustache. Their _old versions contain the originals. Additions are necessary for the header argument in the generated functions so that you can authenticate using cookies.
