Restore link to GitHub actions in GitHub save & sync success toast message

[lmac-1]

Describe the bug The success toast message for Save & Sync does not have the link to GitHub actions as the legacy editor:

Version number v2.15.6

I have reproduced this locally on main:

• Yes
• No

To Reproduce Steps to reproduce the behavior:

1. Save & Sync on a workflow on collaborative editor

Expected behaviour Toast message should have a link in it to GitHub actions

Screenshots

Collaborative editor:

Additional context
This PR should also allow notifications.description to accept JSX as well as a string, so that we can add links in other toast messages.

previous editor success message:

def github_sync_successfull_flash(assigns) do
    ~H"""
    <span>
      Workflow saved and sync requested. Check the
      <.link href={@link_to_actions} target="_blank" class="link">
        Github actions
      </.link>
      for result
    </span>
    """
  end

collaborative editor:

// Show success toast
        const successOptions: { title: string; description?: string } = {
          title: 'Workflow saved and synced to GitHub',
        };
        if (response.repo) {
          successOptions.description = `Changes pushed to ${response.repo}`;
        }
        notifications.success(successOptions);
