Default running against cdw

[gonzoinc]

Please update the salt-lint command to default run against the current working directory. It is very odd to need to build out the find statement to run the linter against all files in a salt repo, that should be default action if no args are present.

I'm not sure if it is very odd -- a quick survey of whether linters and checkers I think of assume this by default:

alejandra: no
ansible-lint: yes
black: no
flake8: yes
ruff: yes
shellcheck: no

I agree that this would be nice, though because salt-lint defaults to looking for init.sls when called on a directory, I don't think it would be as pretty as just defaulting to ..

Globbing is perhaps a briefer way to search in most modern shells (including bash with the globstar option): salt-lint **/*.sls
