Update uncrustify version selection to support >= 0.78.1

[mjcarroll]

This PR updates the Uncrustify version selection logic in ament_uncrustify to support versions >= 0.78.1.

The Problem

Currently, ament_uncrustify hardcodes a check for exactly 0.78.1. If the version differs (even if it is newer), the script falls back to the obsolete 0.72 configuration (designed for RHEL 8 / Ubuntu 20.04).

• RHEL 10 (via EPEL) provides Uncrustify 0.80.1.
• Because 0.80.1 != 0.78.1, RHEL 10 currently falls back to the 0.72 configuration, resulting in thousands of formatting violations in CI.
• Ubuntu 26.04 (Resolute) currently provides 0.78.1, so it passes

The Fix

Updated the logic to use the 0.78 configuration for any version >= 0.78.1. This ensures that the modern style definition is used for the 0.8x family of engines available on RHEL 10 and newer Ubuntu releases.

Test run against RHEL 10

Keeping this as a draft, I'm kind of just hoping that newer config files will be fine then we can figure out what we actually want to do here.

Ah, @cottsay recommended

version = b'0.78.1'
version_tuple = tuple(int(x) for x in itertools.takewhile(bytes.isdigit, version.split(b'.')))

I will do that in a follow-up
