fix(website): show real contributor count on every page shell

The contributor badge rendered 0 on Playbook, Cookbook, home and custom
pages, and reverted to 0 on hydration everywhere else.

Two causes:
- Shells that bypass PageShell (LearningArticleLayout, PlaybookIndex,
  PlaybookArticleBody, CookbookIndex, HomePage, TopNav, Custom) defaulted
  contributorsTotal to 0 instead of the site-data value.
- site-data read .all-contributorsrc with node:fs at module scope. Those
  shells are client:load hydrated, so the read threw in the browser and
  the count reset to 0 after hydration.

The count is now read once in astro.config.mjs and inlined through
vite.define as __CONTRIBUTORS_TOTAL__, so it is a literal in both the
server render and the client bundle.
