Review <Icon> usage

A follow up from https://github.com/patternfly/patternfly-react/pull/11005

In the backstop run for the above PR, I spotted an issue we should look into.

That's from this right-to-left table demo and this file - https://github.com/patternfly/patternfly-react/blob/6b56f7f777129a15c515719a83d8fb45fa812322/packages/react-core/src/demos/RTL/examples/PaginatedTable.tsx#L259-L270

We use <Icon shouldMirrorRTL /> as the preferred way of including an icon that should mirror/flip if the document is set to dir="rtl", so I'm thinking we need to keep that there, and add isInline to let the <Icon> inherit the color and font-size from its parent instead of using our default icon color/size.

And just looking at that demo, looks like we have that same issue in the labels, too. For example, this one https://github.com/patternfly/patternfly-react/blob/6b56f7f777129a15c515719a83d8fb45fa812322/packages/react-core/src/demos/RTL/examples/PaginatedTable.tsx#L212-L221

I updated the first label in the table and added .pf-m-inline to the .pf-v6-c-icon in dev tools and you can see it resized the icon since icons in labels are smaller than our default icon size

I'm not sure how big of a lift it would be, but I would probably suggest we just review each use of <Icon> in the examples/demos and if it's used in a component that wants to style the icon color/size, we consider 1) removing <Icon> if it isn't necessary, and 2) adding isInline if it is necessary.

packages/react-core/src/demos/RTL/examples/PaginatedTable.tsx から始め、特に参照されている paginated-table labels と controls を確認し、関連する backstop result をレビューします。examples と demos の各 Icon の使用について、不要な wrappers や isInline styling の不足がないか確認します。影響を受ける icons が parent の color と size を継承し、必要な箇所では RTL mirroring を維持できれば完了です。
