fix(docs): handle failed release-notes fetch in home.html Hugo build

[Maffooch]

[sc-14595]

Problem

The deploy job in .github/workflows/validate_docs_build.yml (and the github-pages deploy) intermittently fails because Hugo's resources.GetRemote fetches the latest GitHub release at build time and gets a 403 Forbidden (unauthenticated GitHub API rate limit on shared Actions runners).

docs/layouts/home.html called resources.GetRemote without wrapping it in try, so a non-200 response aborted the entire site build:

ERROR error building site: ... GetRemote: failed to fetch remote resource from
'https://api.github.com/.../releases/latest': Forbidden

Fix

Wrap the fetch in try and fall back to an empty release name (the changelog chip is simply omitted) with a warnf, mirroring the resilient handling already in docs/layouts/_partials/header/header.html.

Grepped every resources.GetRemote caller under docs/:

• layouts/home.html — was unguarded → fixed here
• layouts/_partials/header/header.html — already wrapped in try, no change
• layouts/_markup/render-image.html — already wrapped in try, no change

home.html was the only caller that could fail the build.

Verification

Local build with the production config (hugo --minify --gc --config config/production/hugo.toml):

• Normal fetch: builds clean, exit 0.
• Simulated failure (temporarily pointed the URL at a non-existent endpoint): build emits WARN Release notes fetch returned no resource ... and completes with exit 0 instead of erroring. URL restored afterward.
