[Search:Connectors:SyncRules page]Heading levels announced together with buttons elements

[L1nBra]

1.Navigate to button for connector title while using only keyboard by pressing Tab key.
2.Observe screen reader.
3.Press Tab key.
4.Observe Screen reader.
5.Navigate to Edit button for connector title with the keyboard.

NVDA speech viewer + UI elements

html snippet (component which has description element belongs to h1 element)

Actual Result

• Both for title and for description for connector screen reader announces heading level 1; heading level is also announced together with Save, Cancel buttons.

Expected Result

• Heading level is only announced one time (for one element, in this case title of connector). Heading level is not announced for description, nor for Save, Cancel buttons.

This PR #201359 solves the issue regarding wrapping the Title and the Description within the same H1. Now both are siblings and only the Title is wrapped with the H1 tag.

Bearing in mind that:

<EnterpriseSearchContentPageTemplate
      pageChrome={[...connectorsBreadcrumbs, connector?.name ?? '...']}
      pageViewTelemetry={tabId}
      isLoading={isLoading}
      pageHeader={{
        description: connector ? <ConnectorDescription connector={connector} /> : '...',
        pageTitle: connector ? <ConnectorName connector={connector} /> : '...',
        rightSideGroupProps: {
          gutterSize: 's',
          responsive: false,
          wrap: false,
        },
        rightSideItems: getHeaderActions(index, connector),
        tabs: tabs as Array<EuiTabProps & { label: React.ReactNode }>,
      }}
    >
      {selectedTab?.content || null}
</EnterpriseSearchContentPageTemplate>

1. PageHeader.PageTitle renders the content wrapped in a H1 by default
2. Within the ConnectorName we provide. We use and consume this EUI component EuiInlineEditTitle which renders these two buttons. So this part would be so hard to fix due to is part of the global PageTemplate we use. So we should decide if that's OK leaving this buttons within H1 oterwise we should think about remove completely the edit inline feature for titles to get the accessibility compliance. @L1nBra

This EUI doc regarding PageTitle confirms that just passing a regular text is the best option rather than an interactive edit inline component:
