rmk secret edit does not capture keyboard input on linux

[ilya-zlobintsev]

Description

When using rmk secret edit, the opened editor does not capture key presses - instead of passing keys to the terminal, it just overwrites whatever the terminal was showing before.

When using sops directly to edit the file this issue does not occur.

Extra info: this issue happens when using either nvim or nano as $EDITOR, but not with plain vim. vim works fine, but prints a warning: Vim: Warning: Output is not to a terminal.

Steps to reproduce

• Be on Linux
• Open secrets file in an editor with rmk secret edit
• Try using the editor

System info

• rmk version: 0.42.0
• OS: Fedora 40
• Shell: fish (also tried with zsh, the problem remains)
