Requirement for a 6.0 development toolchain: stale docs?

[tristanlabelle]

Description

The Readme states:

This package is under active, ongoing development and requires a recent 6.0 development snapshot toolchain.

But since swift-testing is supported with Xcode 16 which ships Swift 6.0, and the current Swift development version is 6.1, I believe this comment is stale and should read that swift-testing requires Swift 6.0 (or whatever the minimum required version is). Could this notice be clarified?

The comment is still correct(ish) as it's describing the package, not the copy included in the toolchain. The main branch of the package requires either a main-branch or 6.1-branch Swift toolchain to use (anything else might work but is wholly unsupported.)

We should finesse the docs to make that clear.
