Code Review

This pull request modifies ScaffoldPackageCommand.php to ensure that composer.json and the LICENSE file are only updated when the --license flag is explicitly provided. This is achieved by introducing a $license_provided boolean to gate the license-related logic. I have no feedback to provide.

As-is, this PR alone should fix both of @swissspidy's comments:

Hmm I don't like how this now changes the existing MIT license for this project... see #289

That will be super noisy when we get PRs for every package for this. Plus, I'm wary of changing the copyright line like this.

If I don't explicitly pass --license and the project already has a license set, we should not be changing anything.

Skip everything license-related when caling wp scaffold package-readme <dir> [--other-flags] without --license.

Regarding the copyright line changing in this repo's LICENSE file, that's because the copyright line was manually amended (to add contributor credit).

In other words, even before #288 the copyright line in this repo's LICENSE file couldn't be generated like that because it's a manual change. It's not a regression as I first feared. 😅

Skipping all license-related changes if --license isn't given preserves manual changes appropriately now.
