Comment 6 for bug 1892783

Here is the upstream build that corresponds to the topmost commit included in 6.4.6:
https://ci.libreoffice.org/job/gerrit_64/1652/

I found this by finding the topmost merge on the libreoffice-6-4-6 branch (which is where this package would have been built from):
https://gerrit.libreoffice.org/c/core/+/100055

And then tracing back to the ci job. I can add this in future libreoffice SRU descriptions as well.
