Carbon: [DataTableSkeleton] Add prop to hide header in table skeleton

[robherley]

Summary

After #5752 was merged, the DataTableSkeleton component always has a header now, which is a change from how it used to look previously (which is understandable, given the v10 bump).

For the React component, it would be nice to have a prop such as showHeader that can show or hide the extra divs, instead of having to apply some sort of CSS to hide them.

Sounds close to #5967 - CC @carbon-design-system/design

Just to clarify, it's not the header row, it's the new header for the table (container with title & description)

[nictownsend]

This is a breaking change that was not communicated in the release changelog... I'm now forced to override with CSS behaviour that has been forced rather than added as an optional.

[nictownsend]

And it's definitely not a backwards compatible change, so by semver should have been a major version bump.

I'm happy to look at raising a PR if it's acceptable for it to be customisable

@nictownsend My apologies for the change in table skeleton yielded a minor breaking change; The change was meant to be part of v10 but the team slipped it through the crack, and it was seen not worth waiting for v11. A possible future consideration for this area is better release noting.

Wrt providing an option to hide title/description portion, technically it makes sense, but let's see what @carbon-design-system/design thinks from the point of whether our design guide since v10 allows it.

Thank you - for now, the DataTable + DataTable skeleton are not consistent; I use a DataTable without a header or toolbar, and I will have to use CSS to hide the Skeleton header and toolbar for consistency.

If design do not believe the guide for v10 allows a DataTable Skeleton without header/toolbar, then does that also mean the DataTable component (https://www.carbondesignsystem.com/components/data-table/usage) needs updating in the guide to state a Toolbar must always exist?

There are also use cases where you want the DataTable to be a skeleton but you have actions available in the toolbar that do not need a skeleton. For example, the primary button of a table being create new object, which can still occur whilst the underlying data is being refresh (causing a skeleton) e.g.
