This file was supposed to have celery44 dependencies in it but in the last Upgrade Job these were updated mistakenly as they were not constrained. I have done a workaround to keep these requirements constrained and also made necessary changes for celery50 requirements.

[mraarif]

so, we don't want to maintain a celery44 dependencies list?

[mraarif]

maybe we should've added a file for celery50 instead of replacing celery44 with celery50

Latest requirements will only contain packages according to celery52 so adding the suggested step will only create duplicate celery44.txt and celery52.txt files.
In the make upgrade step, we can only fetch the requirements for the latest supported version so the requirements for celery44.txt are being generated with celery44.in now.
