In "Desired/Found", using `quote` inside `add_dep` is printing the AST

### Versions

Elixir: 1.18.4
Erlang: 27

### Operating system

Ubuntu inside Windows WSL

### Current Behavior

Trying to update dependency with `add_dep` like this:

```elixir
|> Igniter.Project.Deps.add_dep(
{:esbuild, "~> 0.10", runtime: quote(do: Mix.env() == :dev)},
)
```

# Current behaviour

In "Desired" and "Found", we get this:

```
Desired: `{:esbuild, "~> 0.10", [runtime: {:==, [context: Phoenix.LiveView.Igniter.UpgradeTo1_1, imports: [{2, Kernel}]], [{{:., [], [{:__aliases__, [alias: false], [:Mix]}, :env]}, [], []}, :dev]}]}`
Found: `{:esbuild, "~> 0.8", [runtime: true]}`
```

For "Desired", the AST of `quote(do: Mix.env() == :dev)` is printed.

For "Found", `Mix.env() == :dev` has been evaluated.

# Expected behaviour

Here is what we should have in best case:
```
Desired: `{:esbuild, "~> 0.10", runtime: Mix.env() == :dev}`
Found: `{:esbuild, "~> 0.8", runtime: Mix.env() == :dev}`
```

### Reproduction

Trying to update a dependency with `add_dep` like this:

```elixir
|> Igniter.Project.Deps.add_dep(
{:esbuild, "~> 0.10", runtime: quote(do: Mix.env() == :dev)},
)
```

Dedicated branch with the issue in a fork of `phoenix_live_view`: https://github.com/phoenixframework/phoenix_live_view/compare/main...aifrak:phoenix_live_view:igniter-issue-add-deps

### Expected Behavior

_No response_

Start at Igniter.Project.Deps.add_dep and reproduce the issue using the dedicated branch linked in the report. Trace how the Desired and Found dependency options are rendered, especially the quoted runtime expression; done means both outputs preserve the intended expression instead of showing an AST or an evaluated value.
