[bare-expo][templates] add gradle.properties to disable runtime sched…

…uler (expo#23117)

# Why

we found some regression in sdk 49 for `useEffect` due to the `unstable_useRuntimeSchedulerAlways` change. though it is unclear how is it going in the meantime. let's add the workaround to disable to `unstable_useRuntimeSchedulerAlways`.

# How

since it is a workaround, i don't want to add the expo-build-properties support. if people come across the useEffect regression and want to test for `unstable_useRuntimeSchedulerAlways=false`. they could have an inline config-plugin

```js
# app.config.js
const { withGradleProperties } = require("expo/config-plugins");

function disableUnstableRuntimeScheduler(config) {
  const KEY = "reactNative.unstable_useRuntimeSchedulerAlways";
  return withGradleProperties(config, (config) => {
    config.modResults = config.modResults.filter(
      (item) => !(item.type === "property" && item.key === KEY)
    );
    config.modResults.push({
      type: "property",
      key: KEY,
      value: "false",
    });
    return config;
  });
}

export default ({ config }) => {
  config.plugins = [...(config.plugins ?? []), disableUnstableRuntimeScheduler];
  return config;
};
```
