Fix exception handling in Microsoft TTS

pycsspeechtts uses the requests library, but Microsoft TTS previously
caught HTTPException from the standard library. This is changed to
catch requests.HTTPError and return `(None, None)` consistent with
other TTS integrations. This will properly raise HomeAssistantError
for display in the frontend.

Follow up to PR #92215 which adds tests for Microsoft TTS.
