MINOR: Don't install Homebrew's Node.js for JNI macOS build (#1270)

The `JNI macos-15-intel x86_64` job currently fails on `main` and on
every open PR while installing dependencies:

```
==> Installing node
Error: node: no bottle available!
This is a Tier 3 configuration:
  https://docs.brew.sh/Support-Tiers#tier-3
Installing node has failed!
`brew bundle` failed! 1 Brewfile dependency failed to install
```

`apache/arrow`'s `cpp/Brewfile` lists `brew "node"`, and Homebrew treats
x86_64 macOS as a tier 3 configuration and no longer builds a bottle for
it. `brew bundle` doesn't build from source, so the step aborts before
anything is built.

We don't need Node.js for the JNI build, so this skips installing it via
`HOMEBREW_BUNDLE_BREW_SKIP`, the same way #1269 did for `aws-sdk-cpp`
and gRPC.

Failing runs for reference:

* `main`:
