Improve logo alt text accessibility and simplify siteConfig destructuring

[Copilot]

Two minor code quality issues in src/pages/index.js: the logo's alt text used an unclear abbreviation, and siteConfig was destructured unnecessarily when only title is consumed.

Changes

• Accessibility: alt="Swob logo" → alt="SMSWithoutBorders logo" — unambiguous for screen readers
• Destructuring: Replaced const { siteConfig } = useDocusaurusContext() + siteConfig.title with direct destructure:

  const { siteConfig: { title } } = useDocusaurusContext();
  // ...
  <Layout title={title} ... />
