Clarify that direct deploys require a glob-compatible path parameter

[filmaj]

Describe the issue
The current CLI reference for deploy makes no mention of the need to pass a path-like parameter to the command. Kind of integral to direct/dirty deploys!

Steps to reproduce
See https://arc.codes/reference/cli/deploy

Expected behavior
We should make that clear.

Additional context
Someone was having trouble with that command on Slack and this issue was a point of confusion! See https://architecture-as-text.slack.com/archives/C6BGT0D08/p1607807121269300

Looking at some open issues. This is an easy change that is still relevant IMO
But I'm wondering if we should remove "dirty" from the docs in favor of "direct". From what I can tell, "dirty" is legacy and just supported in architect/deploy as an alias for "direct" right?

I believe direct is preferred over dirty, though it has never been discussed.
