Couple of odd files at the root of the sfdx project in web console

**Describe the bug**
The tsconfig.json file at the root of the project was confusing to me. It made me wonder things like, 'Can I compile typescript here?' (I know we can't).

We should just verify if the files normally associated with running on local provide any value for web console. The two obvious candidates for removal are
tsconfig.json
jest.config.js

**To Reproduce**
Steps to reproduce the behavior:
N/A

**Expected behavior**
Don't have any files to cause confusing unless they provide value. Shane called out these could provide value for some of the extensions (like LWC)
