bug: asdf version displays the full help output - confusing scripts checking for what asdf is installed

[jaclu]

Describe the Bug

After the rewrite asdf version displays asdf help thus easily confusing scripts detecting what version of asdf is installed.

The version number is still listed on line 1 of the output, so in that sense it could be argued to still be valid output.

However this is not usable in reality, since virtually all version detections are done lazily, assuming the second word is the version, not filtering additional lines of output.

End result: this causes essentially all scripts checking what asdf is installed to fail
