[rubygems/rubygems] Raise a simpler error when RubyGems fails to activate a dependency

Browse Source 
If you force uninstall a dependency but leave other gems depending on
it, those gems will fail to be activated.

In that case, RubyGems prints a rather complicated error:

```
$ rails --version

With this commit, the error becomes a bit simpler to parse:

```
$ rails --version

	from /Users/deivid/.asdf/installs/ruby/3.4.1/bin/rails:25:in '<main>'
```

And also, we reduce exception based control flow in our code.
