fix: Update sdk-client rollup configuration to match common (#630)

This applies the same fixes to `sdk-client` that were applied to
`common`.

This resolves issues with using CJS+Typescript with RN. Our existing
test project doesn't use node16/nodenext module resolution.

Can be tested with our example project with this tsconfig.
```
{
  "extends": "@react-native/typescript-config/tsconfig.json",
  "compilerOptions": {
    "allowSyntheticDefaultImports": true,
    "jsx": "react-native",
    "lib": ["dom", "esnext"],
    "module": "nodenext",
    "moduleResolution": "nodenext",
    "noEmit": true,
    "skipLibCheck": true,
    "resolveJsonModule": true,
    "removeComments": true,
    "sourceMap": true,
    "strict": true,
    "forceConsistentCasingInFileNames": true
  },
  "exclude": ["e2e"]
}
```

Required installing the base config:
```
yarn add -D @react-native/typescript-config
```
