Missing whitespace in `vcpkg portsdiff` output makes parsing output infeasible for long port names

Describe the bug I am interested in parsing the output of vcpkg portsdiff as part of some tooling to automatically update vcpkg manifest files.

Currently a regex like - (\S+)\s+(\S+) -> (\S+) is capable of extracting nearly all port updates, but it fails for ports which have long names due to vcpkg omitting whitespace. A similar issue impacts the "added ports" section, but I'm not currently parsing that.

See https://regex101.com/r/8w4SsK/1 for an example.

Environment

OS: Tested on Linux but expected to be consistent across platforms
Compiler: gcc (GCC) 11.4.1 20231218 (Red Hat 11.4.1-3)

To Reproduce Steps to reproduce the behavior:

./vcpkg portsdiff 101cc9a69a1061969caf4b73579a34873fdd60fe 821100d967e1737d96414a308e3f7cbe0d1abf18
Observe the output for the azure-storage-* ports.

Expected behavior vcpkg portsdiff should always have at least one whitespace character between the port name and port version.

Additional context Maybe there's another entrypoint I should be going through to extract this data?
