help users with zsh

zsh is installed by default on macs and this is a bad experience as I just used what worked on bash + on the docs:

$ driftctl scan --from tfstate://**/*.tfstate
zsh: no matches found: tfstate://**/*.tfstate
$ bash
bash-3.2$ driftctl scan --from tfstate://**/*.tfstate
Scanned states (3)
Found resources not covered by IaC:
  aws_internet_gateway:
    - igw-01f1b9d38973e31ce
[...]

On zsh we should use something like driftctl scan --from 'tfstate://**/*.tfstate'

Let's update the docs!

It works well with bash too:

bash-3.2$ driftctl scan --from 'tfstate://**/*.tfstate'
Scanned states (3)
Found resources not covered by IaC:
  aws_internet_gateway:
    - igw-01f1b9d38973e31ce
[...]

Why not documenting using the quotes be the default?

Search the documentation for the driftctl scan example using tfstate://**/*.tfstate. Update the default command to quote the glob, then check the rendered example against the bash and zsh behavior shown in the issue; done means the documented command works in both shells.
