fix(electron): correcting package.json versions (#1267)

<!-- CURSOR_SUMMARY -->
> [!NOTE]
> **Medium Risk**
> Adjusts `peerDependencies` for Electron packages, which can change
install-time compatibility for consumers using older Electron versions.
No runtime logic changes, but dependency resolution/build pipelines may
be affected.
> 
> **Overview**
> Updates Electron package manifests to better reflect supported
Electron versions.
> 
> `@launchdarkly/electron-client-sdk` now declares an Electron peer
requirement of `>=34.5.6` (instead of `*`), and the `example` and
`contract-tests` packages add explicit `peerDependencies` matching their
Electron devDependency versions.
