(PA-8499) Relax commander constraint

In Ruby 3.4, abbrev was promoted from a default gem to a bundled gem.
highline 1.x/2.x require abbrev and now fail to load under Ruby 3.4
unless an explicit dependency on it is declared. highline 3.0 removed
that dependency.

commander pins highline transitively: 4.x requires highline ~> 2.0,
and only commander 5.0 requires highline ~> 3.0. Relaxing the upper
bound to '< 6' lets vmfloaty resolve to highline 3.x on Ruby 3.4+
while still allowing commander 4.x for older consumers.
