fix(aria-allowed-role): add form to allowed roles of form element (#4588)

matuzo · straker · commit d462d674bb7d · 2024-10-16T10:48:39.000-06:00
The ARIA in HTML spec [allows a form element to have role=form](https://www.w3.org/TR/html-aria/#allowed-aria-roles-states-and-properties#el-form), but [axe does not allow it](https://github.com/dequelabs/axe-core/blob/develop/lib/standards/html-elms.js#L264). This PR adds form to the allowedRoles of form.
