370 again integration test failures because of snapshot changes

[BFalquet]

https://github.com/insightsengineering/teal.modules.hermes/issues/370

This is a prototype to replace the plot snapshot testing and avoid test failure due to minimal changes in the plotting.

• introduce a test argument in the barplot module. If TRUE, the structure (layer_data) of the plot is rendered.
• the snapshot test is now performed on the underlying data rather than on the plot itself

thank you for your review and suggestions
