community/yash: upgrade to 2.53
https://github.com/magicant/yash/releases/tag/2.53
- Changed: The shell now deterministically rejects arithmetic expansions that result in undefined behavior.
- Fixed: A non-interactive yash now exits on an assignment error in a for loop.
- Fixed a bug where command substitutions contained in the regular expression inside the
[[ word =~ regex ]]syntax were not parsed correctly.- Fixed a bug where unclosed quotes in an end-of-here-document indicator were causing the shell to crash or misbehave.
- Fixed a bug where yash crashes when invoked with no argv.
