Inputrc mode conditions not handled

[DirtYiCE]

Description

I just updated to ruby 3.3.0 and got this thing instead of readline, and I immediately ran into a few issues.

1. As far as I can see, it doesn't even attempt to parse /etc/inputrc, which is also a standard location.
2. Condition support is lacking. Here it looks like it treats almost everything as false:

   reline/lib/reline/config.rb

   Line 235 in 38e9cb2

   when 'mode'

   . This also means that is skips most of the standard gentoo inputrc which is inside a $if mode=emacs ... $endif, so for example no history search mapped to Page up/down.

Minimized inputrc that shows the problem:

$if mode=emacs
# map "page up" and "page down" to search history based on current cmdline
"\e[5~": history-search-backward
"\e[6~": history-search-forward
$endif

What are your expected behavior

It works like readline if this expected to be a drop-in replacement.

actual behavior of your environment?

It's practically unusable without making a reline specific inputrc and making sure I only export INPUTRC for ruby processes.
