Follow up is the dude from flickr gets lens model info in his images by right-clicking jpg image in the folder where the images are located in Windows. Click "properties" then "details". As you scroll down in "details" there's area where it says "lens model". Click into the blank space and input info.
That's consistent with what I saw when I looked at that JPEG. The XMP metadata is missing a whole lot of stuff Adobe software would write, and exiftool complains about a nonstandard field Microsoft added to it.
Also using exiftool, I can see that his camera writes "135mm" for the lens name, just as my EOS body writes "100mm" for my ZE lens. Either the lenses are sending back a blank string for the lens name, or they are sending "100mm" or "135mm" as the names (this is transmitted over the lens contacts when you mount the lens; recent Canon lenses send their full name).
I'll repeat what I said above: it's the postprocessing software which writes the lens names for non-Canon lenses. For example, Adobe writes one name for my Zeiss 100mm, and DxO writes a slightly different one; that's why, to make them the same, I run my DxO-processed images through a script to change the lens name to the Adobe convention.
If you're using DPP to do the raw conversion and then putting the TIFFs into Lightroom, you won't get the lens name. Canon aren't going to do that for third party lenses.
If you're using Adobe to do the raw conversion, make sure you are enabling XMP on export. It should *also* be in the EXIF, but I'm not seeing it there in that user's Flickr image. That might be a difference between Lightroom and Adobe Camera Raw (that user did the conversion in the latest version of Lightroom on Windows, and I use ACR), or it might be a difference in the way Adobe handle .CR2 and .CR3. Either way, just the XMP should be sufficient for Flickr to show the lens name, because it's using exiftool behind the scenes.
You would be making more progress with your question if you uploaded a JPEG or raw sample where people here could download it, instead of guessing at solutions. I don't have a software tool for .CR3, but I can at least look at the JPEG and raw with exiftool.
