ability to disable cache for preview of text files

[srghma]

problem

1. open joshuto
2. hover on file
3. see preview 1
4. enter, edit, exit
5. expected - see edited version, actual - I see old version and have to reload joshuto to see new file version

my config

https://github.com/srghma/dotfiles/blob/main/joshuto/preview_file.sh

P.S. in ranger if return exit code e.g. 0 - success and cache, 5 - success and no cache
