fix(illustrated-message): center actions slot content

[cdransf]

Description

Wraps the slot[name="actions"] in a .swc-IllustratedMessage-actions div with display: flex; justify-content: center so that buttons and button groups placed in the actions slot are horizontally centered, consistent with the illustration, heading, and description above them.

Motivation and context

When PR #6454 added slot="actions" support to swc-illustrated-message, the slot was placed as a direct child of .swc-IllustratedMessage-content (a flex column). That container uses text-align: center for inline text but has no align-items: center, so block-level slotted content defaulted to left-aligned. The fix follows the existing wrapper pattern already used for .swc-IllustratedMessage-description.
