## Summary
This PR applies the auto-fix for the newly introduced
`@elastic/eui/require-aria-label-for-modals` Ensures that EUI modal
components `EuiConfirmModal` have either an `aria-label` or
`aria-labelledby` prop for accessibility. This helps screen reader users
understand the purpose and content of modal dialogs.

## Changes

- For **function components**:
1. Verify whether `useGeneratedHtmlId` is imported from the
`@elastic/eui` package. If not, add the following import.
2. Inside the render method, define a new constant: `const
confirmModalTitleId = useGeneratedHtmlId();`
- For **class components**:
1. Verify whether `htmlIdGenerator` is imported from the `@elastic/eui`
package. If not, add the following import.
2. Inside the render method, define a new constant: `const
confirmModalTitleId = htmlIdGenerator()('confirmModalTitle');`

In both cases, add the following props to the `EuiConfirmModal`
component:
- `aria-labelledby={confirmModalTitleId}`
- `titleProps={{ id: confirmModalTitleId }}`
