Simplify the jq command used to read version inside build_android (#55057)

Summary:
This is a pick of 4cac35f7d03f4000f100d3e98514b135422c37b6 inside `main`.
The commit is already on the `0.84-stable` branch.

The reasoning here is that `cat` + `jq` failed to run with:

```
Run echo "rn-version=$(cat packages/react-native/package.json | jq -r 'version')" >> $GITHUB_OUTPUT
  echo "rn-version=$(cat packages/react-native/package.json | jq -r 'version')" >> $GITHUB_OUTPUT
  shell: bash --noprofile --norc -e -o pipefail {0}
jq: error: version/0 is not defined at <top-level>, line 1:
version
jq: 1 compile error
```

I'm moving to a single `jq` invocation as it's more resilient.
