Fish <enter> won't work with ${ENV}

[r4v3n6101]

Description
Any action that involves opening a file via ${EDITOR} will fail in case the fish is set as shell. It's caused by unsupported ${} by fish (instead needed `{EDITOR}).

Example
Any file opening with fish. It may be files, todo-comments and so on channels.

Expected behavior
Calling /bin/sh maybe.

Environment

• OS: MacOS
• TV version: 0.15.2
• shell: fish
• terminal: kitty
• The channel you are using: files

Additional context

fish: ${ is not a valid variable in fish.
${EDITOR:-vim} 'Cargo.lock'
