cabal repl other-package doesn't open repl

**Describe the bug**
When I call `cabal repl package-name` for some dependency in the current project, `cabal` accepts the argument, builds it, and then just exits.

**To Reproduce**
Steps to reproduce the behavior:

```
$ cd Cabal
$ cabal v2-repl filepath
Resolving dependencies...
Up to date
$ echo $?
0
```

**Expected behavior**
I'd expect either an error telling me what I'm trying to do doesn't make sense, or a repl prompt.

**System information**
- Operating system: macos
- `cabal` 3.6.2.0 & recent HEAD, `ghc` 8.10.7

**Additional context**
What I was actually trying to do is bring an indirect dependency into scope. A repl within http-conduit which depends on http-client which pulls in network-uri, and I can't interact with the URIs I get out of some of the things I have in scope. Not sure `cabal repl network-uri` should have helped with that, or what would be the best way to achieve that.
