What does this PR do?

Fixes a malformed markdown table in the Integrations overview doc. The "Voice & TTS Providers" table had stray leading double-pipes (||) on its separator row and every data row, which broke rendering in Docusaurus — readers saw an extra empty leading column and misaligned cells. Changing each || to | restores a properly-aligned 4-column table.
