fix: adjust path on tryRequire to handle dep check

[mmason2-godaddy]

Summary

• Why: The checkDevDependencies function wasn't behaving properly due to the path used in the tryRequire. A require on @docusaurus/core will always return null. Opt for a tryRequire on the package.json of that file.
• What: Adjust path on the tryRequire

Changelog

• adjust path on tryRequire to handle dep check

Test Plan

• Update test case with the new path

Seems fine as a workaround since there's not an alternative. My main worry is that if this package changes its internal structure this could break, but if this is how Docusaurus code imports from @docusaurus/core I guess any changes to the structure would be a breaking change anyway. Another option may be to import @docusaurus/core/package.json (they could break that in the future as well, though, if they messed with the exports declarations)

I'll give this a shot real quick. That's a good alternative.
