FindRuby: Rename variables to match case of module name
Use recommended case for variable names, i.e. matching name of the
module as passed to find_package
.
For backwards compatibility, the upper case versions of both input and output variables are used and defined when appropriate. Skip this for the _FOUND variable because FPHSA already does it.
This follows the approach from commit a7b09e7f that made the equivalent change for FindProtobuf
.

Not sure if I need to provide backward compat for RUBY_FIND_VERSION_MAJOR
, RUBY_FIND_VERSION_MINOR
, RUBY_FIND_VERSION_EXACT
. FindProtobuf doesn't do that.
