Since #3227 we get the following warning in the various data visualizations:

VisibleDeprecationWarning: sc.DataArray.attrs has been deprecated and will be removed in Scipp v24.12.0. The deprecation includes sc.DataArray.meta and sc.DataArray.drop_attrs. For unaligned coords, use sc.DataArray.coords and unset the alignment flag. For other attributes, use a higher-level data structure.

We should hide this in:

• html_repr
• sc.table
• sc.show
• identical?
• assert_identical?
