Fails to resolve on Swift `6.2.3` under macOS `15.7.3`

[xsyetopz]

Describe the bug
It tells us that latest package is depending on unstable version of swift-subprocess while expecting for stable version.

To Reproduce

1. Have machine with macOS Sequioa (15.7.3) installed.
2. Have Swift 6.2.3 (according to swiftc -- version) installed.
3. Try adding package dependency to Packages.swift.

Expected behavior
Expected being able to have resolved packages in Packages.resolved and not be errored out.

Screenshots
Not screenshot, but terminal output:

'swiftterm' >= 1.9.0 cannot be used because no versions of 'swiftterm' match the re
quirement 1.9.1..<2.0.0 and package 'swiftterm' is required using a stable-version but 'swiftterm' depends on an unstable-v
ersion package 'swift-subprocess'.
