rolling: rebuild plotjuggler with the refreshed patch

[Tobias-Fischer]

#67 refreshed rolling's ros2-plotjuggler.patch (3.17.2 already wraps the message in a Span), but the published build 29 predates it. build_number: 30 gets the patch built and published. The humble patches from #67 are picked up by the humble rosdistro sync (#62), which is a full rebuild.

pixi run sort --check and rs check pass, and the generated recipe has number: 30.

Compared with the newest builds on https://repo.prefix.dev/tobias-fischer/robostack-distro-test/linux-64 and https://repo.prefix.dev/robostack-rolling/linux-64.

Exported symbols are compared (the released packages are stripped, so struct layouts aren't); unchanged installed headers rule out layout and inline changes, changed ones are listed for review. Dependents to rebuild are the released ones linking to a changed library. A changed pin is part of the comparison.
