Replace bun with node in local-package-repository script (#2319)

## Motivation for the change, related issues

Running `npm run local-package-repository` returns the following error
when running the `cli.ts` file with `bun` :

```
17 | // OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE
18 | // USE OR OTHER DEALINGS IN THE SOFTWARE.

20 | "use strict";

         ^
error: The module 'fs_ext' was compiled against a different Node.js ABI version using NODE_MODULE_VERSION 131. This version of Bun requires NODE_MODULE_VERSION 127. Please try re-compiling or re-installing the module.

```

Bun's most recent version `1.2.17` requires `NODE_MODULE_VERSION` 127.
This means we have to compile `fs_ext` with Node20.

@bgrgicak What do you think of replacing `bun` with `node` instead to
avoid that issue and the rebuild process?

## Testing Instructions

`npm run local-package-repository`
