fix: Move test-snaps dependencies to devDependencies (#3758)

The `test-snaps` NPM package includes the full bundle including all
dependencies and thus does not need to have any NPM dependencies.

Fixes #3738 

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> Relocates all `packages/test-snaps` runtime dependencies into
`devDependencies`, removing the `dependencies` section.
> 
> - **Package metadata** (`packages/test-snaps/package.json`):
> - Move all entries from `dependencies` to `devDependencies` and remove
`dependencies`.
> - Ensure tools/libs like `@metamask/providers`, `react`, `react-dom`,
`react-bootstrap`, `react-redux`, and `bootstrap` are listed under
`devDependencies`.
>   - No other script or config changes.
