Update property-information dependency version range

[iansan5653]

Allow 6 or 7 versions of property-information.

After hastscript's 9.0.1 release, hast-util-to-parse5 is now the only holdout preventing us from fully upgrading and deduplicating property-information. There doesn't appear to be any breaking changes in the major update from 6 to 7, so it should be pretty straightforward to just declare this package compatible with the latest version.

I kept 6.x as an option just to make the change even easier, but I can just make it only ^7.0.0 if you prefer.

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and discussions and couldn’t find anything or linked relevant results below
• I made sure the docs are up to date
• I included tests (or that’s not needed)
