Xcode 26 appears to handle build scripts differently, can break previously working Patrol integration

[ewann]

Steps to reproduce

1. Follow the getting started guide for iOS up to https://github.com/leancodepl/patrol/blob/master/docs/getting-started.mdx?plain=1#L413 or https://github.com/leancodepl/patrol/blob/master/docs/getting-started.mdx?plain=1#L536 for MacOS
2. Paste the entire script over the top of the existing /bin/sh, instead of leaving /bin/sh in place, and using the script box for this text

Actual results

Prior to Xcode 26, this appeared to work as intended, and the scripts would run successfully.

Apparently on Xcode 26.0.1 (17A400) this no longer works, resulting in some confusing/misleading errors that can be avoided by using the approach demonstrated in https://www.youtube.com/watch?v=zwQB8LfnTN8&t=926s at the ~15 min - ~15.26 min mark.

Unfortunately, I spent some time before reaching this understanding.

I'm happy to PR a clarification / screenshots about this for iOS & MacOS, but based on https://github.com/leancodepl/patrol/blob/master/CONTRIBUTING.md and not quickly finding how to build the docs locally, decided to submit it here first for feedback.
