Add Skip Link to Bypass Table

[SamiyahKey]

Story

As a keyboard-only user,
I need a skip link that allows me to bypass the table in the main content area and jump directly to the filters,
So that I can efficiently navigate the page without unnecessary repetition.

URL: Domain Request (/admin/registrar/domainrequest/)

Acceptance Criteria

• Add a skip link at the top of the page and just above the table to allow users to bypass the table and navigate directly to the filters.
  Example: <a href="#filters" class="skip-link" aria-label="Skip to the filters section">Skip to filters</a>
• The skip link should be visually hidden but accessible via keyboard and become visible when focused.
• Screen readers must announce the presence of the skip link using correct ARIA labels in programmatic markup, providing clear context for its function.
• Confirm with a designer that the implementation adheres to WCAG 2.4.1 and 2.1.1

Additional Context

• Ensure skip links are compatible with various assistive technologies.
• Test the implementation to confirm that the skip link is accessible in different browser and screen reader combinations.
