`--repl-multi-file` doesn't seem to play nice with older versions of GHC

**Describe the bug**

I am trying to use `--repl-multi-file` to simplify `cabal-doctest` (https://github.com/sol/doctest/issues/428) and make it more robust.

The documentation of `--repl-multi-file` states:

> Write repl options to this directory rather than starting repl mode

Given this, I would assume that

```
$ cabal repl -w $GHC
```
and

```
$ cabal repl --repl-multi-file ./tmp -w $GHC
$ $GHC --interactive `cat ./tmp/*-inplace`
```

are essentially equivalent.

However, this doesn't seem to be the case. While the earlier works for a wide range of GHC versions, the later does not work with versions of GHC older than 9.4.*.

**To Reproduce**

```
$ git clone https://github.com/sol/markdown-unlit && cd markdown-unlit
```

```
$ GHC=ghc-9.2.8
```

```
$ cabal repl -w $GHC
```

```
$ cabal repl --repl-multi-file . --keep-temp-files -w $GHC
```
```
$ $GHC --interactive `cat markdown-unlit-0.6.0-inplace`
...
ghc: unrecognised flag: -this-package-name
...
```

**Expected behavior**

```
$ cabal repl -w $GHC
```
and
```
$ cabal repl --repl-multi-file ./tmp -w $GHC
$ $GHC --interactive `cat ./tmp/*-inplace`
```
behave the same, at least in a none-multi-repl scenario.

**System information**

`cabal-install-3.12.1.0`

Start with the `cabal repl --repl-multi-file` path and reproduce the markdown-unlit example using GHC 9.2.8 and cabal-install-3.12.1.0. Compare its generated options with direct `cabal repl` and verify that invoking `$GHC --interactive` from the generated `*-inplace` file behaves equivalently on older GHC versions.
