Modify parser.rb to add a colon between each term and the line break, which `ronn` converts into a definition list.
The <br> that follows ensures each term description is on a new line in the manpage output, and also replaces the
double trailing space for generating the hard return that follows each term in the HTML output.
Also modify man.rb to print environment variables with list markup matching the cask commands, and then drop
trailing colons from both lists of terms (cask commands, env vars) and non-list terms (analytics, bundle, services;
a <br> is added here because it would prevent the term description from being indented in the manpage output).

Fix `-1` and other flags so they're handled correctly with casks. Use
the "right" exceptions for declaring invalid combinations and change
their parent class so that `--help` is printed nicely too.
Fixes#9033
The refactor in 6e8f5d0958247e4b4d629866099ed2836a0e0863 means that the
exception no longer exposes the name of the package with multiple versions,
and as a result the rescuer is unable to print this information.
Because we now have a path in which MultipleVersionsInstalledError doesn't
have the name at all, we can't reasonably restore the old behaviour.
And since rack resolution happens purely internal to the function that
raises the exception, the caller has no way to know what name to use.
However, since the exception text gets printed anyway, we can just move
this text into the exception itself.
Fixes the following error:
```
Error: mpd has multiple installed versions
Error: undefined method `name' for #<MultipleVersionsInstalledError:0x00007fc6009d8870>
