## Summary
Updates `ts-loader` to `9.5.7` so ncc's bundled TypeScript loader
preserves configured `rootDir` during `transpileModule` builds.
This fixes TypeScript 6 `TS5011` failures like:
```text
TS5011: The common source directory of 'tsconfig.json' is './actions/javascript/...'. The 'rootDir' setting must be explicitly set to this or another path to adjust your output's file layout.
```
`ts-loader` fixed this upstream in
https://github.com/TypeStrong/ts-loader/pull/1679.
## Verification
- Ran `yarn build`
