fix: Prefix the publishable package path with ./

When trying to call the `.publish` rule on a publishable `npm_package` in a non-root BUILD file, currently the call to `npm` does not find the given package and interprets the argument as a git repository `github.com/path/to.git` .  Specifically if you have a package rule in a first-level drectory, e.g. `ts/BUILD.bazel` contains a `npm_package(name = 'foo'...` then calling `npm publish ts/foo` will attempt to `git ls-remote https://github.com/ts/foo.git`.

npm/cli#2796 implies that this is a behaviour change and we need to prefix a `./` to force it to find this argument as a filesystem path.  This does indeed work in my local testing.
