fix(sourcemap-support): add "tslib" as a dependnecy for "sourcemap-su…

…port" (#670)

Compiled code of this package requires "tslib" to be installed
which is not the case if the porject has "@swc-node/register"
as a single dependency.

In that case `npm` will generate the following tree:

```
- node_modules
  - @swc-node
    - sourcemap-support
    - register
      - node_modules
        - tslib
```

and `tslib` will be insaccessible for "@swc-node/sourcemap-support"
