refactor!: change Package API

This changes the following public APIs:

**(_breaking_) Events on the `Package` class**
The `uninstall:success` event on the `Package` class now receives an `InstallReceipt` as argument, instead of an
`InstallHandle`. This receipt is an in-memory representation of what was uninstalled. There's also a new
`uninstall:failed` event for situations where uninstallation for some
reason fails. Note: this also applies to the registry events (i.e.
`package:uninstall:success` and `package:uninstall:failed`).

---

**(_breaking_) `Package:uninstall()` is now asynchronous and receives two new arguments, similarly to `Package:install()`**
While package uninstallations remain synchronous under the hood, the public API has been changed from synchronous ->
asynchronous. Users of this method are recommended to provide a callback in situations where code needs to execute after
uninstallation fully completes.

---

**(_breaking_) `Package:get_install_path()` has been removed.

---

**`Package:install()` now takes an optional callback**
This callback allows consumers to be informed whether installation was successful or not without having to go through a
different, low-level, API. See below for a comparison between the old and new APIs:
```lua
-- before
local handle = pkg:install()
handle:once("closed", function ()
    -- ...
end)

-- after
pkg:install({}, function (success, result)
    -- ...
end)
```
