Collecting texture maps with cliique assemble after the update of the bug fix on the UDIM context data

          **Not crucial for this PR, but something to consider over time?**

This may actually fail for published UDIM files from Substance Painter integration with the default template because the UDIM tile I believe is separated by _ instead of . so there will still only ever be one dot in the filename.

As such, I wonder. Do we still need the len(filename.split(".")) > 2 check?

Beware that _1001.exr may not be picked up by the clique.assemble call either with the "frames" pattern because I believe that may also require a dot as number separator. So allowing publish/v001/udim/texture_1001.exr may require more fixes than just removing that if statement check. :)
