feat!: Allow specifying many options in config profile without array

[aawsome]

Breaking change:
password-command and warmup-command now must be given as array if the commands use args.

LGTM

To be honest, I think this is slightly annoying. I can no longer copy-paste the command directly into a shell to test that it works.

@intgr I got your point. So maybe we should allow both: a single string which would be automatically split into its parts and an array to cover complicated spacing.... I'll discuss this with the other maintainers..

@intgr After a short discussion we decided that we want to support a single string. So this change will be kind of reverted/overworked.

Thanks for working in supporting the single string configuration for "password-command" again.

Would be great to also include a more clear message when the failure related to that configuration change is triggered.

Example: I still had the "old" configuration with password-command = "secret-tool lookup ...", which now it gives just a single line of error like when running rustic:

error: No such file or directory (os error 2)

It took a while to identify where the error was triggered, and the "no such file" was quite misleading 🤯
Adding some context on the error might help

I also experienced this and submitted a PR to improve the situation: rustic-rs/rustic_core#265
