Fetch name argument from other_options using fetch

[chhtz]

(instead of named parameter)

This fixes an error which made using e.g. oroshell (but probably anything capable of introspecting orogen tasks from ruby) unusable in ruby 3.x.

I have no idea if this is the right way to fix this

With ruby 2.7 this fixes a warning:

/opt/workspace/tools/orocos.rb/lib/orocos/ruby_tasks/task_context.rb:45: warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
/opt/workspace/tools/orocos.rb/lib/orocos/ruby_tasks/task_context.rb:61: warning: The called method `initialize' is defined here

With ruby 3.2 this fixes an error:

/opt/workspace/tools/orocos.rb/lib/orocos/ruby_tasks/task_context.rb:66:in `initialize': wrong number of arguments (given 2, expected 1) (ArgumentError)
	from /opt/workspace/tools/orocos.rb/lib/orocos/ruby_tasks/task_context.rb:50:in `new'
	from /opt/workspace/tools/orocos.rb/lib/orocos/ruby_tasks/task_context.rb:50:in `new'
	from /opt/workspace/tools/orocos.rb/lib/orocos/base.rb:304:in `initialize'
	from /opt/workspace/tools/orocos.rb/bin/oroshell:18:in `<main>'

This PR is definitely not enough. E.g., trying to use Orocos.get will lead to similar errors with wrong number of arguments.
I can dig deeper into that, but I'd first need to know what the correct way to handle named+hash parameters is.

This is the right interface. What needs to be changed is the caller.

Can you show me the calling code ?

I'm hopeful I'll have the opportunity to start working on ubuntu >= 24.04 soon ... Sorry I can't directly help so far.

The callstack is in the main comment, but it looks like I didn't remove my debug code before copying the error. Direct caller was in line 45:

        remote_task = super(local_task.ior, name: name, model: model, **options)

I think it would already help fixing all warning: Using the last argument as keyword parameters is deprecated; (these happen in ruby 2.7 already, and apparently break with ruby 3.x).

Addendum: This warning occurs directly, e.g., when calling oroshell on the command line.
