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.

Start with packages/react-core/src/demos/RTL/examples/PaginatedTable.tsx, especially the referenced paginated-table labels and controls, and review the related backstop result. Check each Icon use in the examples and demos for unnecessary wrappers or missing isInline styling. Done means affected icons inherit their parent color and size while retaining RTL mirroring where needed.
