chore: remove duplicate cli resource files (#129)

CLI derivative packages should never check-in their own version of CLI
resource files (bootstrap template, init templates, etc.). Instead they
are expected to copy any required files over at build time.

This PR removes the checked-in version of `init-templates` and bootstrap
template from `cli-lib-alpha`.
It also adds respective gitignore and npmignore rules.

Note that neither `cli-lib-alpha` nor `toolkit-lib` currently support
the init command and therefore don't need the templates just yet.
