feat(builder-bob): dont use npm bin to get tsc path (#435)

## Summary

Closes #434
The builder bob typescript build phase uses `yarn bin` and `npm bin`
commands to locate the `tsc`. However, the `npm bin` command is removed
with npm 9.0. Please see:
https://github.blog/changelog/2022-10-24-npm-v9-0-0-released/

## Test plan

> Both of the test cases start with the following steps:
1. Clone the repo and cd into `packages/react-native-builder-bob`
2. Run `yarn prepack` to build the builder bob.
3. Run `npm link`
4. Create a new project with `npx create-react-native-library@latest
my-awesome-project`. You can select `javascript` as the type.
5. Run `npm link react-native-builder-bob` to link the project.

### Resolve `tsc` automatically

1. Run `npm run prepack` to verify the typescript compilation step works
properly.
2. Run `yarn prepack` to verify the typescript compilation step works
properly.
3. Run `pnpm prepack` to verify the typescript compilation step works
properly.

### Resolve `tsc` using the builder bob config

1. Go to the `package.json` file of the project you've generated.
2. Go to the `react-native-builder-bob` section and specify the tsc
binary as following: (the `tsc` line needs to be added.)
```json
  "react-native-builder-bob": {
    "source": "src",
    "output": "lib",
    "targets": [
      "commonjs",
      "module",
      [
        "typescript",
        {
          "project": "tsconfig.build.json",
          "tsc": "./node_modules/.bin/tsc"
        }
      ]
    ]
  }
```
3. Run `npm run prepack` to verify the typescript compilation step works
properly.
4. Run `yarn prepack` to verify the typescript compilation step works
properly.
5. Run `pnpm prepack` to verify the typescript compilation step works
properly.
