fix: update semantic-release and @semantic-release/npm to stable versions (#17)

## Problem

`@semantic-release/npm@13.0.0-alpha.5` depends on
`npm@github:npm/cli#oidc`, but the `oidc` branch has been deleted from
the `npm/cli` repo, causing `npm install` to fail:

```
npm error command git --no-replace-objects checkout oidc
npm error error: pathspec 'oidc' did not match any file(s) known to git
```

This breaks all downstream release workflows (e.g.
[cnpm/unpkg-white-list](https://github.com/cnpm/unpkg-white-list/actions/runs/22700918457/job/65844808852)).

## Fix

- `@semantic-release/npm`: `13.0.0-alpha.5` → `^13.1.5` (stable, uses
`npm@^11.6.2` from registry)
- `semantic-release`: `25.0.0-alpha.4` → `^25.0.3` (stable)
