fix(pods): Fix invalid react-native/../react-native resolution for aliases (#4232)

## Description

Related:
software-mansion/react-native-reanimated#9592
(same fix for `react-native-reanimated` and `react-native-worklets`)

The pod script attempts to resolve `react-native/package.json` to get to
the `version` and perform a version check. It however performs a
redundant `react-native/../react-native` resolution i.e. it essentially
performs `path.dirname(require.resolve('react-native/package.json'))`
(correct), but then joins this with `${dir}/..`, then re-joins this with
`react-native`.

Re-entering the `react-native` directory can be invalid in case of
symlinks in the `node_modules` structure. The easiest way to reproduce
an issue is to use react-native-tvos's pattern of aliasing
`"react-native": "npm:react-native-tvos@x.x.x"`. With isolated
dependencies this will point a symlink at a directory that's named
`react-native-tvos` and not `react-native`. The also applies to local
`link:` dependency specifiers. Essentially, the directory name
`react-native` is unnecessarily enforced.

This would lead to a cryptic `file: no implicit conversion of nil into
String.` error

## Test plan

- Existing `pod install` in working projects should continue passing
unchanged
-
https://github.com/kitten/douglowder--with-monorepo-tv-test/tree/init-pnpm
- `pnpm i` then in `apps/tv` run `pnpm prebuild` (which runs `pod
install`)
