Set minimum swift version to 5.8 (#822)

Fix deprecation warning when targeting macOS 13 (#814)

Another attempt at #710

Short description:

Fixes this deprecation warning when targeting macOS 13:

```
Sources/XcodeProj/Extensions/String+md5.swift:63:16: warning: 'init(bytesNoCopy:length:encoding:freeWhenDone:)' was deprecated in macOS 13: String does not support no-copy initialization
        return String(bytesNoCopy: ptr, length: hexLen, encoding: .utf8, freeWhenDone: true)!
```

Solution:

* cherry-picked an [updated version from swift-crypto](https://github.com/apple/swift-crypto/blob/606608da0875e3dee07cb37da3b38585420db111/Sources/Crypto/Util/PrettyBytes.swift#L40-L54)

add precompiled header extension to headersExtensions for adding .pch…

… to public header section by tuist (#812)

Version 8.18.0
