ci: install libasound2-dev so the studio's audio backend builds on Linux (#184)

Preview audio (#182) added rodio, which pulls cpal, which needs ALSA's
development headers on Linux. The build was only ever checked on macOS, where
cpal goes through CoreAudio and alsa-sys never enters the graph — so main went
red on merge and every PR opened after it inherited the failure.

Same line as the webkit/gtk/xdo deps already there, in both jobs.
