Documents the two official PostHog OpenFeature providers for JavaScript (@posthog/openfeature-node and @posthog/openfeature-web): installation, usage, evaluation-context mapping, supported flag types, and options.

Move installation and usage instructions out of the package READMEs and into the PostHog docs (companion PR PostHog/posthog.com#18105), so the guidance lives in one place and doesn't drift. Same approach as the Python provider. Each README keeps a short description and a link to the docs page. Generated-By: PostHog Code Task-Id: 46a3f8c9-fbcd-460e-9457-fca583955e5a

What
Adds docs for the two official PostHog OpenFeature providers for JavaScript, mirroring the existing OpenFeature (Python) page:
@posthog/openfeature-node-provider— server/Node.js, backed byposthog-node+@openfeature/server-sdk@posthog/openfeature-web-provider— browser, backed byposthog-js+@openfeature/web-sdkNew page at
/docs/feature-flags/installation/openfeature-jscovering installation, usage, evaluation-context mapping, supported flag types, and options for both providers, plus a nav entry next to the Python one.Companion PR
Implementation: PostHog/posthog-js#3994 (the two provider packages). Usage instructions live here in the docs rather than the package READMEs so they stay in one place and don't drift — same approach as the Python provider.
