Re-add outputName to _rename_in_representation

[EmberLightVFX]

Changelog Description

This PR simply adds new_repre["outputName"] = output_name inside the _rename_in_representation function.
Without this if a user would like to add eg {colorspace} to a name preset it wouldn't be found, so you can't have two oiio outputs as the second one would try and overwrite the first publish.

Additional info

This bug was found by @jakubjezek001 under the hackinton but I'm submitting it as we fixed in on my ayon instance.

Testing notes:

1. add <_{colorspace}> to your render name preset
2. add two oiio conversion presets
3. publish a render

Without this fix you'll get an error that it can't publish an already published product. With the fix + _{colorspace} added to the name Ayon will be able to publish the new oiio products with new correct output names.
