build(deps-dev): update rouge requirement from ~> 5.0.0 to ~> 5.1.0 in /gem

[dependabot]

Updates the requirements on rouge to permit the latest version.

Release notes

Sourced from rouge's releases.

v5.1.0

This release adds a new lexer for AddmusicK/Ramekin assembly and a substantial overhaul of the Perl lexer. The Java lexer now supports more modern syntax and no longer splits import static into separate tokens. The Shell lexer gains support for bash 5.3 curly substitutions and bitwise shift operators in math contexts. We also improved comment handling in Makefile body blocks and added delimited comment support to VHDL, along with fixes to the AppleScript, Markdown, Properties, Vue, and YAML lexers.

Thanks to all our contributors for your help and continuous support!
