Joshua May 13afb8b802 Use supplied path when installing plugin from NPM to prevent escaping issues (#3825 )

Summary:
Resolves https://github.com/facebook/flipper/issues/3819

This PR fixes Flipper's plugin installation, so that scoped plugins (with `/` in the name) can be successfully installed (+removed).

In more detail, Flipper's function [`installPluginFromNpm()`](69bac4a3d6/desktop/plugin-lib/src/pluginInstaller.tsx (L99-L114)) relies on the `live-plugin-manager` package to handle the NPM package to a temporary directory.

Before this patch, Flipper would assume the name of the directory (incorrectly). This patch simply uses the directory as provided by `live-plugin-manager`'s result.

If we use `shopify/flipper-plugin-react-native-performance` as a concrete example after this patch:

- `installPluginFromNpm()` is called to install `shopify/flipper-plugin-react-native-performance`
- `plugManNoDep.install()` installs the plugin to `/path/to/tmp/shopify/flipper-plugin-react-native-performance`
  - note: before this patch, it would have been assumed to be installed to: `/path/to/tmp/shopify__flipper-plugin-react-native-performance` which does not exist
- `installPluginFromTempDir()` is called to install the package to `~/.flipper/installed-plugins/shopify__flipper-plugin-react-native-performance/{version}` (where `{version}` is the current version, i.e. `1.0.0`)

Once the plugin is in `~/.flipper/installed-plugins/`, the escaping is correctly applied consistently by Flipper, and there are no further issues managing/using the plugin.

## Changelog

Fixed errors when installing scoped NPM plugins

Pull Request resolved: https://github.com/facebook/flipper/pull/3825

Test Plan:
Ideally we'd have some unit tests, but mocking out the NPM fetching in `live-plugin-manager` seems like a bunch of work. If you have some shortcuts, let me know, because this would be useful to test across platforms.

But in the meantime, we can easily manually test this.

### Reproduce the failure

First, let's reproduce the failure:

- run Flipper 0.150.0 (or `yarn start` on master, etc)
- open plugin marketplace, attempt to install scoped plugins
- installation will fail (with ⚠️ icon)

- logs will show a failure to read `package.json`

### Demonstrate success

- run Flipper from this branch (via `yarn start`)
- open plugin marketplace, attempt to install scoped plugins
- installation will succeed, with notification to restart Flipper

- (package can also be successfully used/upgraded/uninstalled)
