docs(enterprise): fix broken helm-charts links on Platform Helm page

[rnaidu-seqera]

Problem

A customer reported (FD-7794) that the example values file link on
Platform Helm returns a 404.

They were right, and it's not the only one — all four helm-charts links on that page are broken.

Root cause

The seqeralabs/helm-charts repo was restructured. Two changes broke these links:

1. Charts moved from <root>/platform/ to <root>/charts/platform/.
2. Platform chart tags were renamed from bare 0.36.1 to prefixed platform-0.36.1 (there is no 0.36.1 tag anymore).

Fix

Link text	Before (404)	After (200)
Helm chart	tree/0.36.1/platform	tree/platform-0.36.1/charts/platform
example values file	blob/0.36.1/platform/examples/kustomize/values.yaml	blob/platform-0.36.1/charts/platform/examples/kustomize/values.yaml
README	tree/0.36.1/platform	tree/platform-0.36.1/charts/platform
Kustomize example directory	tree/0.36.1/platform/examples/kustomize	tree/platform-0.36.1/charts/platform/examples/kustomize

Applied to all five copies of the page — the current doc set plus version-26.1, version-25.3, version-25.2, and version-25.1. (version-24.2 and earlier don't have this page.) 20 changed lines, URLs only, no prose changes.

Note that the current doc set already had the platform- tag prefix on all four links but was still missing charts/, so it was 404ing too.

Verified

Every URL in the diff status-checked at 200; a grep for the old forms (helm-charts/{blob,tree}/0.36.1 and platform-0.36.1/platform) now returns nothing across both docs trees.

The helm-charts links in studios-helm.md, groundswell-helm.md, install-groundswell.md, co-scientist/prerequisites.md, and install-seqera-coscientist.mdx were also checked and all return 200 — their tags predate the restructure or already point at master/charts/... — so they are intentionally untouched.

Out of scope (flagging for the docs team)

• Chart version pin. The page pins 0.36.1 throughout, including in the helm show values / helm install --version examples. Latest is platform-0.38.0. I deliberately did not bump it — that's a content-freshness call, not a link fix, and a released version's docs arguably shouldn't move. Worth a look for the current doc set though.
• CI gap. The weekly Links workflow globs './**/*.mdx' only, so the 1,896 .md files in this repo — including every platform-helm.md — are never link-checked, which is why this went unnoticed. Follow-up PR opened separately against .github/workflows/links.yml.
