Use yarn v3 instead of v2

[Quantalabs]

Updates the gitignore for Node to use yarn v3 instead of yarn v2. Ignores the files recommended by yarn on the docs.

Reasons for making this change:

Yarn v3 has a different ruleset than yarn v2, ignoring everything except the patches, plugins, releases, sdks, and versions in the .yarn/ folder. My changes update the gitignore to support these changes.
