fix(vue): support kebab-case icon-node prop on Icon component (#4512)

* fix(vue): support kebab-case icon-node prop on Icon component

The Icon component destructured `iconNode` camelCase-only while
`stroke-width`/`absolute-stroke-width` accept both cases, so the
idiomatic Vue usage `<Icon :icon-node="..." />` left iconNode undefined
and crashed with 'Cannot read properties of undefined (reading map)'
(#3485). Accept the kebab-case alias and guard the render path.

Closes #3485

* Potential fix for pull request finding
