Check version script is not validating if the release candidate versions is the same for iOS

[pedroferreira1]

We have a script that runs in the CI to check if all versions are equal among all files that have them, e.g., package.json, build.gradle, and project.pbxproj.

However, for the iOS version, we only validate the first part of the version, without the release candidate number (rcX).

The script validates only if the release candidate number is in a valid format, i.e., [0-9].[0-9].[0-9].

We must improve the script to validate that this format matches the other versions' release candidate number, and, if it's not a release candidate, if the format is 1.0.0, as expected.
