Fix Subprocess.run API updates

Fixes the API breakage introduced in swift-subprocess 0.5 by swiftlang/swift-subprocess#233.

It looks like we'll also need to drop the jammy swift:6.1.3 jdk:corretto CI matrix element due to swift-subprocess dropping support for Swift 6.1 (swiftlang/swift-subprocess#231), since the CI is failing:

Computing version for https://github.com/swiftlang/swift-subprocess.git
error: Dependencies could not be resolved because root depends on 'swift-subprocess' 0.5.0..<1.0.0.
'swift-subprocess' >= 0.5.0 cannot be used because no versions of 'swift-subprocess' match the requirement 0.5.1..<1.0.0 and 'swift-subprocess' 0.5.0 contains incompatible tools version (6.2.0).

I'm guessing this won't be an issue since we document Swift 6.2 as being the minimum required version in the README anyway.

This is causing the swift-android-examples to fail to build with the errors:

273 |     error: .standardError,
274 |   )

An alternative solution could be to pin swift-subprocess to 0.4 as per the recommendation in the release notes. But assuming that everything else works as expected, the simple renaming fix seems easy enough.

I’ll have to double check if we need 6.1 in some adopters… thank you for the pr!
