[garysassano]

Describe the bug

As per title, NodejsFunction currently doesn't support Bun's new text-based lockfile introduced in v1.2.0, which is now the default.

Error: Cannot find a package lock file (`pnpm-lock.yaml`, `yarn.lock`, `bun.lockb` or `package-lock.json`). Please specify it with `depsLockFilePath`.
