Fix: maintain alphabetical ordering of combined Paseo test endpoints

The index.spec.ts test suite enforces that all "Test networks" and "Paseo & parachains" endpoints are alphabetically sorted by their text value.

After adding the Shibuya Testnet (Astar) entry to testParasPaseoCommon, the combined list in testRelayPaseo.linked no longer met that requirement:

• testParasPaseo (regular parachains) ends with Zeitgeist Battery Station (Z...)
• testParasPaseoCommon (common chains) begins with Asset Hub (A...)

When these arrays were concatenated, the overall result was not alphabetically sorted, causing the test failure:

AssertionError [ERR_ASSERTION]: Test networks:: Ajuna Network (Paseo) needs to be before Shibuya Testnet (Astar)

To ensure consistent ordering regardless of future additions, the final combined list is now explicitly sorted by text:

linked: [
  ...testParasPaseo,
  ...testParasPaseoCommon
].sort((a, b) => a.text.localeCompare(b.text)),

This guarantees that the global alphabetical check passes and prevents similar regressions if new endpoints are appended later.
