Make official forest-trail APIs easier to discover

Add the Korea Mountaineering and Trekking Support Center's 17-API collection as one curated catalog entry and align both language variants with the current document date.

Constraint: Link to the provider's official collection page while acknowledging that individual specifications and key issuance route through the Public Data Portal.

Rejected: Add seventeen separate rows | A grouped provider entry avoids catalog noise and duplicate maintenance.

Confidence: high

Scope-risk: narrow

Directive: Keep the API count synchronized with the provider page and avoid duplicating its individual trail endpoints.

Tested: Python aiohttp check returned HTTP 200 for the official index and all 17 linked Open API detail pages; one entry per README; current date appears twice per language; git diff --check.

Not-tested: Authenticated calls to the 17 underlying APIs were not executed.
