Aliases are not supported by `--execute`

[nikelborm]

Describe the bug

freeze --execute doesn't interpret aliases or functions

To Reproduce

1. Open the terminal and enter this

alias ll='eza -labgM --group-directories-first --no-time --octal-permissions --classify=always --icons=always --color-scale=size --color-scale-mode=gradient --color=always --hyperlink --smart-group --no-quotes -h'

freeze --execute ll

2. Observe error

                              
   ERROR  Something went wrong
                              
  could not execute: exec: "ll": executable file not found in $PATH

Expected behavior

Makes a screenshot.

Workaround

# paste this function into .bashrc
plain_alias () 
{ 
    alias $1 | grep --color=never -oP "(?<=').*(?=')"
}

# run 
freeze --execute "$(plain_alias ll) /"
