[release] debugAdapter: fix a bug where we are not sending back configuration done response

This change is to address this bug: eclipse-theia/theia#8455. The Go extension is not able to continue past after hitting the breakpoint because `setConfigurationDoneRequest` is not sending back a response if the program is already running. This keeps Theia waiting for the response (which it never receives!).
