Fix alignment with available commands

When upgrading the Color package from `v1.15.0` to `v1.16.0`, the list
of available commands becomes incorrectly aligned:

```text
Available Commands:

  completion Generate the autocompletion script for the specified shell
  help      Help about any command
  test      Test command for clarity
```

This was related to an [issue][1] where reset codes were not correctly
set. The [fix][2], which added extra reset codes, increased the length
of the string (which includes the ANSI codes) causing the amount of
padding to be insufficient.

This change, which upgrades the Color package to `v1.16.0`, also
increass the padding to account for the additional ANSI reset codes
that are now part of the string. This restores the text alignment to
how it was previously displayed.

Unit tests also needed to be updated to account for this change and are
passing successfully.

The Color package had updated its dependencies which has caused the
changes in `go.mod` to impact more than itself.
