Add 'Open in Studio' CTA to every cookbook page

Each cookbook page now links its template to the Studio editor via
<StudioTemplateLink template="<slug>" />, placed under 'The Complete Schema'.
Resolves to the org-agnostic editor entry (studio.formance.com/ledger-schemas/
editor?template=<slug>), which forwards to the reader's org or the public editor.
The StudioTemplateLink component lives in the docs repo (registered as a global
MDX component, like LedgerSchema).
