Improve yanked gem error message

The problem was that the error message for a yanked Gem told the user to:

> update your bundle to a different version of foo (1.0)

This is slightly misleading because in this example, foo 1.0 is the version that has been yanked. They should use any verion of foo **other** than 1.0.

My diagnosis was that the error message interpolated the gem specification (which converts to a string as "NAME (VERSION)") rather than just the name of the gem in this instance.

My fix was to change that occurrence of the gem specification to just the gem name.

I chose this fix because it was the only way that occurred to me to do it.
