fix: include required messagingpush dependency for no push configuration

[levibostian]

The RN SDK today does require the messagingpush SDK module but the podspec that we ask customers to install does not include this module. This could mean compile-time errors.

Yes, we do expect that customers setup rich push in their app and so we do not expect customers to encounter this problem. However, the idea that this PR also adds a comment to the podspec files specifying required dependencies is a good value add to the codebase.

PR in draft mode and asks for review by team to get feedback if this is something we want to do or not.

Note: Conversation that sparked this idea: https://github.com/customerio/docs/pull/1446#discussion_r1298239891

Pull request title looks good 👍!

If this pull request gets merged, it will cause a new release of the software. Example: If this project's latest release version is 1.0.0. If this pull request gets merged in, the next release of this project will be 1.0.1. This pull request is not a breaking change.

All merged pull requests will eventually get deployed. But some types of pull requests will trigger a deployment (such as features and bug fixes) while some pull requests will wait to get deployed until a later time.

This project uses a special format for pull requests titles. Don't worry, it's easy! This pull request title should be in this format: ``` : short description of change being made ``` **If your pull request [introduces breaking changes](https://web.archive.org/web/20220725195319/https://nordicapis.com/what-are-breaking-changes-and-how-do-you-avoid-them/)** to the code, use this format: ``` !: short description of breaking change ``` where `` is one of the following: - `feat:` - A feature is being added or modified by this pull request. Use this if you made any changes to any of the features of the project. - `fix:` - A bug is being fixed by this pull request. Use this if you made any fixes to bugs in the project. - `docs:` - This pull request is making documentation changes, only. - `refactor:` - A change was made that doesn't fix a bug or add a feature. - `test:` - Adds missing tests or fixes broken tests. - `style:` - Changes that do not effect the code (whitespace, linting, formatting, semi-colons, etc) - `perf:` - Changes improve performance of the code. - `build:` - Changes to the build system (maven, npm, gulp, etc) - `ci:` - Changes to the CI build system (Travis, GitHub Actions, Circle, etc) - `chore:` - Other changes to project that don't modify source code or test files. - `revert:` - Reverts a previous commit that was made. ### Examples: ``` feat: edit profile photo refactor!: remove deprecated v1 endpoints build: update npm dependencies style: run formatter ``` Need more examples? Want to learn more about this format? [Check out the official docs](https://www.conventionalcommits.org/). **Note:** If your pull request does multiple things such as adding a feature _and_ makes changes to the CI server _and_ fixes some bugs then you might want to consider splitting this pull request up into multiple smaller pull requests.
