Bartek Iwańczuk d17f4590a2
feat(init): add --npm flag to initialize npm projects (#26896) 
This commit adds support for `deno init --npm <package>`.

Running this will actually call to `npm:create-<package>` package that
is equivalent to running `npm create <package>`.

User will be prompted if they want to allow all permissions and
lifecycle scripts to be executed.
Closes https://github.com/denoland/deno/issues/26461
