[dependabot]

Bumps tailscale/github-action from 2 to 4.

Release notes

Sourced from tailscale/github-action's releases.

v4.0.0

With this release, the action is now implemented in JavaScript and requires runners that are capable of installing Node.js 24.

Notable changes:

• New: Now supports a ping parameter to verify connectivity to tailnet devices.
• New: Now logs out the Tailscale ephemeral node at the end of the CI run, removing it from the tailnet immediately.
• Changed: Caching of Tailscale binaries is enabled by default.
• Fixed: DNS resolvers are properly set on macOS. Previously, attempting to reach devices using their full domain of the form my-node.my-tailnet.ts.net would fail due to incorrect DNS settings.
