wezel: Use bundle-linux for size measurements (#65234)

## Summary

Right now we're measuring size of artifacts from `cargo b --release`,
which doesn't match what we're actually distributing.

## Testing

Manually test your changes; report results, mention platforms if
relevant.
How can reviewers test this easily? Include setup and steps.

## Self-review

- [ ] I've reviewed my diff for quality, security, reliability, and
performance.
- [ ] UI changes follow the
[checklist](https://zed.dev/docs/development/ui-checklist).
- [ ] Tests cover the new or changed behavior.

Release Notes:

- N/A
