Symfony's ConsoleQuestion does not support key navigation

[diegoe]

When editing the answers to the interactive add command, I run into this. Seems Symfony doesn't support keyboard navigation in line answers!

Upstream: symfony/symfony#36657
Original readline support: symfony/symfony#16458
Upstream PR, but died in draft: symfony/symfony#36700

@diegoe, thanks for the report!

Indeed, it would be nice to have that ability.

As you point out, it is likely something that should be implemented at Symfony console component.

The work-around for me is just add the text as it is on the prompt, but later

1. edit the YAML manually, let us remember that

   YAML is a human friendly data serialization standard for all programming languages.

2. and then run the formatter import/export process to make sure the YAML is in machine friendly idempotence.
   i.e. contriblog format

Please let me know if I misunderstood the request, and if it is something to do upstream.
Feel free to close it since implementing it at this project may likely be out of scope.

@diegoe I think PR #2 will solve this nicely.
