chore: Upgrade peer dependency ink

[jlarmstrongiv]

Closes #71

I updated the PR to fix xo linting errors from updates to https://github.com/sindresorhus/eslint-plugin-unicorn 👍 triggering another workflow run would be great!

CI is failing. Make sure npm test succeeds locally.

[jlarmstrongiv]

Not sure why, but I was only able to get ava to run tests by setting NODE_OPTIONS directly avajs/ava#2593 (comment)

Please try re-running the CI. While some tests were timing out due to my local environment, I am more confident the CI should pass.

Ink 5 requires Node.js 18, so to support that, we also need to require it. Also update the Ink dev dependency so we can be sure it works.

Alrighty, I originally thought it may be possible for pastel to support both ink v4 and v5, but I have changed it to require ink@5 and nodejs >=18 👍 tests still seem to pass, but you’ll need to run the workflow to confirm

Last but not least, as the minimum version of node has changed, I bumped pastel a major version to v3

I bumped pastel a major version to v3

Don't make unrelated changes.
