Requires bug-id to be passed and toggles the corresponding bug open or
closed (`gbo <bug-id>`). Otherwise just passes through any arguments to
the `git-bug bug status` command.
The alias `gb` will list all bugs (or allows to query for them) by
default. But if only a single argument is provided, and that argument is
a bug id then it shows the bug.
This allows a nice workflow like:
```sh
$ gb
# -> returns list of bugs, pick one from it
$ gb <bug-id>
# -> returns detailed description of bug
```
