Install Linux dependencies for Wezel runs (#64475)

The first dispatched binary-size run failed while compiling `x11`
because the stock `ubuntu-latest` image did not include Zed's Linux
build dependencies. The old Wezel runner incorrectly reported that as a
successful empty run.

Run Zed's existing `./script/linux` setup before the Wezel action,
matching Zed's Linux CI jobs.

Release Notes:
- N/A
