fix(ci): pulseaudio headers, and an ASCII release payload

Linux got past pipewire and stopped on pulse/pulseaudio.h — the module
compiles both backends, so both sets of headers are needed.

Windows reached the upload and Gitea rejected the release creation with HTTP
422, 'invalid UTF-8 within /name': the JSON body carried accented text and the
Windows runner's shell mangles the encoding on the way out. The payload is now
ASCII, with a comment saying why, so it does not get 'improved' back into
Portuguese.
