Disable authentication check, but keep runnable

chemotaxis · chemotaxis · commit b0f58d0cf05e · 2021-06-18T23:43:42.000-04:00
In this branch, we originally avoided the authentication check by
getting rid of the run method attached to the command.  Instead of that,
this commit makes the `gh actions` command runnable again, but the
authentication is disabled with `cmdutil.DisableAuthCheck`; this mirrors
what's done for `gh version`.

`gh actions` and `gh actions [-h | --help]` all work while being logged
out.

In addition, this commit restores some original behavior.  Before this
commit, the help footer (usage, inherited flags, etc.) is appended
whether you use `gh actions` or `gh actions --help`.  This commit
restores the original behavior where `gh actions` prints just the text
for the actions explanation, but `gh actions --help` appends the help
footer.
