What?

Adds a new CMS-editable landing-page block, VersionSupportTable, that renders a
Payload version support/status grid. Each row exposes editable fields for Payload
Version, Release Date, Critical Fixes Until, Security Fixes Until, and a Status
select (stable / beta / eol) rendered as a colored badge.

Why?

There was no reusable, content-managed way to display version support/EOL
information on marketing pages. This lets editors maintain the support matrix
directly from the admin UI without code changes. This can be linked to from Docs as the source of truth.

How?

• New block definition in src/blocks/VersionSupportTable/index.ts
  (interfaceName: VersionSupportTableType).
• React component + SCSS module in src/components/blocks/VersionSupportTable/,
  modeled after the existing ComparisonTable block (16-column Gutter grid,
  colgroup with explicit column widths, horizontal-scroll on mobile).
• Registered the block in payload.config.ts, added 'versionSupportTable' to
  the Pages layout blockReferences, and mapped it in RenderBlocks.
• Regenerated payload-types.ts.
