Extension `.js` apears in TS files when importing a schima [TypeScript, OS X, FlatBuffers 23.5.26]

Hello!

Even though I generate the TS files using the `--ts-no-import-ext`, when you have an import in one of your schemas, the TS file will still contain an export with a `.js` extension:

If I have the following schemas:

```fbs
// color.fbs

enum Color:byte { Red = 0, Green, Blue = 2 }
```

```fbs
// monster.fbs

include "color.fbs";

namespace Sample;

table Monster {
color:Color = Blue; // Enum.
}

root_type Monster;
```

After running `flatc --ts --ts-no-import-ext -o monsters_generated monster.fbs` we get a file monster.ts with the following content:

```ts
// automatically generated by the FlatBuffers compiler, do not modify

export { Color } from './color';
export * as Sample from './sample.js';
```

Thank you!
