feat(create-docusaurus): enable creation in current directory

[Mcheung7272]

Pre-flight checklist

• I have read the Contributing Guidelines on pull requests.
• If this is a code change: I have written unit tests and/or added dogfooding pages to fully verify the new behavior.
• If this is a new API or substantial change: the PR has an accompanying issue (closes #0000) and the maintainers have approved on my working plan.

Motivation

It'd be nice to create a new docusaurus project inside of a directory instead of using a subfolder and a subsequent command to move the files to the correct parent folder.

Test Plan

1. Yarn build
2. Create a test folder at root level
3. cd to test folder and run node ../packages/create-docusaurus/bin/index.js . classic --typescript
4. Confirm new docusaurus project is created inside the current directory (ie test)
