docs(shell-docs): fix broken Action Handlers link in a2ui fixed-schema page (#6764)

The "Advanced — Action Handlers" link pointed to
`./advanced#action-handlers`, but there is no `advanced.mdx` page in
`docs/generative-ui/a2ui/`. The "Action handlers (reference)" section
lives in this same file, so the link now points to it directly with
`#action-handlers-reference`.
