ci(mobile): symlink react-native CLI for CodePush OTA bundling (#14387)

## Summary
- Fixes Mobile OTA Release (CodePush) jobs failing with
`node_modules/.bin/react-native: not found` (exit 127). Example: [run
26308703765](https://github.com/AudiusProject/apps/actions/runs/26308703765/job/77452051457).
- After [#14365](#14365)
regenerated the lockfile, `react-native` (and the bin from
`@react-native-community/cli`) hoists to the monorepo root
`node_modules/`, so `packages/mobile/node_modules/.bin/react-native` no
longer exists.
-
[`@bravemobile/react-native-code-push@12.3.2`](https://app.unpkg.com/@bravemobile/react-native-code-push@12.3.2/files/cli/dist/functions/runReactNativeBundleCommand.js)
hardcodes the relative path `node_modules/.bin/react-native` (cwd is
`packages/mobile`) when invoking `react-native bundle`, so the lookup
fails.
- Add a symlink step before `npx code-push release` in both
`mobile-ota-release` and `mobile-ota-release-production` that points
`packages/mobile/node_modules/.bin/react-native` at the hoisted root
binary.

## Test plan
- [ ] Mobile OTA Release (CodePush, ios) on this PR's merge to `main`
succeeds (or workflow_dispatch w/ `rc` channel).
- [ ] Mobile OTA Release (CodePush, android) on this PR's merge to
`main` succeeds.
