ci(openfeature-node-server): fixing release please settings

[joker23]

This PR will update the configuration for packages/sdk/openfeature-node-server in release please to:

1. fix the extra-file reference since the example is in a subdirectory of the workspace
2. set release-as to 1.3.0 to get this package ready to publish from this repo

---

Note

Low Risk
Changes affect release automation and documentation only; no runtime SDK behavior is modified.

Overview
Updates release-please so the OpenFeature server packages can ship stable versions from this repo instead of staying on prerelease bumps.

For packages/sdk/openfeature-node-server, it sets release-as: 1.3.0, drops bump-minor-pre-major, and fixes the extra-files JSON path to examples/getting-started/package.json (workspace-relative) so the getting-started example dependency version is updated on release. For packages/shared/openfeature-server-common, it replaces prerelease settings with release-as: 1.0.0.

Docs cleanup aligns with GA: experimental/pre-release CAUTION blocks are removed from both OpenFeature READMEs and NPM/CI badges are enabled. The openfeature-node-server CHANGELOG is reset to a bare header (prior version entries removed), consistent with a fresh release line.

closing this as I think we could just do the release.
