Add testing setup

[kevinramharak]

Fixes #4

This PR implements:

• using vitest as a test runner with its browser mode
• a check on GameConfig.banner !== false before logging the phavuer banner to the console
• some basic tests for the Game component

Notes: The addition of:

  "resolutions": {
    "string-width": "^4.2.2"
  }

is needed because of https://github.com/isaacs/jackspeak/issues/5. Long story, but it comes down to require/esm being a huge mess when coupled with npm dependency hell.

@kevinramharak Thank you! I haven't been able to confirm the details yet, but it seems that the following error occurs when I run yarn run test.

$ yarn run test
yarn run v1.22.10
$ vitest

 DEV  v1.3.1 /home/laineus/works/phavuer-kevin

@laineus I'll take another look, I noticed weird behaviour based on whether node_modules was already present or not. There are 3 packages that have this ESM/CJS mess. I think all of them are a dependency of cliui so maybe I can pin that to a working version.

[kevinramharak]

@laineus This is caused by a resolution bug in yarn v1. The package jackspeak updated cliui to ^8.0.1 here which causes this mess, although its really a yarn v1 problem that is fixed in version 2.

I pinned jackspeak to 2.1.1 as suggested here, that seems to work, you might have to remove node_modules once because it seems yarn is stubborn on keeping the old broken packages even though the package.json and yarn.lock list different versions.

@kevinramharak It's working correctly now! Since there are no issues, I'll merge it.

Thank you for the great work!
