CodeBlock - aria attributes need updating in examples

[thatblindgeye]

Describe the enhancement or change
For both examples, the aria-label of the buttons should be updated:

• the copy button should have an aria-label that conveys what will be copied, e.g. Copy to clipboard basic example code block.
• The "play" button aria-label shouldn't have the word "icon" in it and either just be "Play" or follow the ClipboardCopy additional actions example and use "Run in web terminal" -- this should also have a tooltip aplied to it.

For the expandable example, the aria-labelledby on the expandable content points to a non-existent ID. Passing the same toggleId to both ExpandableSection and ExpandableSectionToggle will resolve this.

Is this request originating from a Red Hat product team? If so, which ones and is there any sort of deadline for this enhancement?

Any other information?
