feat(amazonq): Pass project configuration to LSP client (#7162)

## Problem
The LSP server accepts local VSCode workspace configurations for AmazonQ
upon initialization, but they are not being passed to the client by the
VSCode extension. See
https://github.com/aws/language-servers/blob/main/server/aws-lsp-codewhisperer/src/shared/amazonQServiceManager/configurationUtils.ts

## Solution
* Add missing settings for file indexing to the extension
* Pass the workspace settings to  Flare when the client is instantiated

## Testing

/>

I confirmed that Flare is receiving the data and that it can parse it
