WCAG 2.5.3: Module lifecycle links aria-label diverges from visible text [#3611421]

Problem

WCAG 2.5.3 Label in Name requires that the accessible name of a control contains the visible label text. In four files across the system module, lifecycle status links (e.g., "(Experimental)", "(Deprecated)") have an aria-label that does not contain the visible link text.

Visible text: "(Experimental)" or "Experimental"

Accessible name: "View information on the Experimental status of the module Node"

A speech recognition user who says "Click Experimental" may not match because the accessible name starts with "View information on", not "Experimental".

Proposed resolution

Change the aria-label to start with the visible link text. For modules (visible text is in parentheses):

'aria-label' => $this->t('@lifecycle (status information for @module)', [
  '@lifecycle' => ucfirst($lifecycle),
  '@module' => $module->info['name'],
]),

For themes (visible text has no parentheses):

'aria-label' => $this->t('@lifecycle (status information for @theme)', [
  '@lifecycle' => ucfirst($lifecycle),
  '@theme' => $theme->info['name'],
]),

For the non-stable confirm form, remove the leading space and fix the mismatch:

'aria-label' => $this->t('The @name module is deprecated. (more information)', [
  '@name' => $name,
]),
