Custom command passing a string literal

[pythoninthegrass]

Describe the bug
Running an ad hoc docker run command in the terminal works. Passing the same command to lazydocker as either a scalar (folded/literal) or inline fails.

To Reproduce
Steps to reproduce the behavior:

1. Create a custom command in config.yml

   - name: run-meetup
     attach: true
     command: >
       docker run -it --name meetup_bot
       -p 80:3000
       -e PORT="3000"
       -v "$(pwd)":/home/appuser/app
       --env-file .env
       meetup_bot
       bash

   or

   - name: run-meetup
     attach: true
     command: 'docker run -it --name meetup_bot -p 80:3000 -e PORT="3000" -v "$(pwd)":/home/appuser/app --env-file .env meetup_bot bash'

2. Open lazydocker
3. Run the command
4. Raises error:

   + docker run -it --name meetup_bot -p 80:3000 -e PORT=3000 -v $(pwd):/home/appuser/app --env-file .env meetup_bot bash
   
   docker: Error response from daemon: create $(pwd): "$(pwd)" includes invalid characters for a local volume name, only "[a-zA-Z0-9][a-zA-Z0-9_.-]" are allowed. If you intended to pass a host directory, use absolute path.
   See 'docker run --help'.

Expected behaviour
It should interpolate/expand the pwd command or $PWD built-in variable in the command. Only able to hard-code the absolute path to work around the issue. Less than ideal, of course.

Screenshots
N/A

Desktop (please complete the following information):

• OS: macOS 12.4 (21F79)
• Lazydocker Version: v0.18.1
• The last commit id if you built project from sources: N/A

Additional context
Using the new docker mount syntax got the same results.

$(pwd) have to run in the shell, but lazydocker seems like run command directly.
I think this is not bug, but run commands through shell will be more convenient I think.

[pythoninthegrass]

What would you suggest the workflow should be if this isn't a bug @skanehira?

[jesseduffield]

I agree, we ought to run all custom commands in a shell so that things like $(pwd) can be evaluated. We do that currently with lazygit

[jesseduffield]

The place we could update is here. In lazygit we have a NewShell function which takes a command and wraps it in a shell invocation (see here) so we can copy that approach in lazydocker

I'll tackle this one.

go ahead @gusandrioli :)

Appreciate the follow-up! 🙏
