fix(amazonq): Add Open tab as params for inline completion (#7801)

## Problem
aws/language-server-runtimes#638

The workspace.getAllTextDocuments() API only returns the open tabs that
were clicked during this IDE session. If you open, close, reopen IDE,
this API returns empty unless user re-click those files again.

So we need to let IDE compute the list of open tab files and send it to
language server

## Solution

Pass open tabs from the IDE to language server.
This is not customer facing so there is no change log needed.
It merely brings back old functional code.
