Add ability to customize the rspec command.

[lucasprag]

This is needed because people might want to run rspec using
foreman or docker like foreman run bundle exec rspec --color

Hi 👋

Thanks for building this great extension. I was using it and I felt the need to customize the rspec command to prepend foreman. I've seen in plugins for other editors that they just let the user be able to customize the entire command so I did exactly that.

As the updated readme says the user can customize the rspec command using the vscode settings like:

{
  "vscode-run-rspec-file.custom-command": "foreman run bundle exec rspec --color",
}

and the default is bundle exec rspec --color

Maybe in the future we can update the rspec command based on projects somehow.

Thanks for reviewing @thadeu =)

I just found out that we can overwrite any settings per project using the .vscode/settings.json file. That's cool 😎 . So I added a one line description to let people know since it's quite relevant in this case. Is that ok @thadeu?

[thadeu]

@lucasprag if configuration is empty or not exists? we should be return default value "bundle exec rspec --color" right?

[lucasprag]

oh yeah, I did that in my first version, but eventually I saw that there is an option to set the default in the configuration file so I did it here.

Suggested change

	return vscode.workspace.getConfiguration().get(SETTINGS_RSPEC_COMMAND_KEY);
	let configCommand = vscode.workspace
	.getConfiguration()
	.get(SETTINGS_RSPEC_COMMAND_KEY);
	return configCommand || "bundle exec rspec --color";

So we don't need this based on my comment above, thanks =)

This is exactly what I was looking for, thanks both for all your efforts! Can't wait to give this a go as we run our projects from inside Docker and so need to configure the command too <3
