Update SwiftSyntax to unbreak macro modules.

[scottrhoyt]

SwiftSyntax 601.0.0 is missing the marker module SwiftSyntax601, meaning that it'll break builds (primarily macro modules) that support large version ranges of SwfitSyntax via #canImport(SwiftSyntax601) directives. This has been fixed in 601.0.1, but SwiftLint via SPM will keep the graph pinned against the broken 601.0.0 (like here). The only change of note from 601.0.0 -> 601.0.1 was adding the missing marker module, so this should be an easy fix on the SwiftLint side.

This also unlocks SwiftLint and dependent modules being able to use the preview for prebuilts in SPM for SwiftSyntax, which knocks a significant chunk off of compile time.

Thanks!

I only updated the Bazel dependency likewise and rebased to resolve the build issues.
