* build: switch main to track main from swift-syntax

This changes the build to track main, which is required when building
against the latest toolchain.  This allows us to build
SwiftSyntaxHighlighter on Windows with the latest toolchain.

* Revert "build: switch main to track main from swift-syntax"

This reverts commit efaf5da.

* Add version-specific manifests for Swift 5.4 and 5.5

* Update Xcode versions in CI workflow
