Lightning is requiring packaging < 25.0

[thebaptiste]

Bug description

Is there a reason for lightning requiring packaging < 25.0 ?

The last lightning release allowing an install with packaging==25.0 is lightning==1.8.6 (try pip install lightning==1.8.6 packaging==25.0, it works !)

Yet packaging 25.0 does not seem to be revolutionary...

So may be you could remove the upper limit on packaging ?

By the way, I'm not very found of upper limits in dependencies, unless you are sure there will be a problem with the next releases of your dependencies... This was probably not the case here, as the release 25.0 of packaging did not exist when you choose to set packaging<25.0 in your dependencies...

What version are you seeing the problem on?

v2.5, v2.4, v2.3, v2.2, v2.1

How to reproduce the bug

for example : 

pip install lightning==2.5.1.post0 packaging==25.0

Error messages and logs

ERROR: Cannot install lightning==2.5.1.post0 and packaging==25.0 because these package versions have conflicting dependencies.

The conflict is caused by:
    The user requested packaging==25.0
    lightning 2.5.1.post0 depends on packaging<25.0 and >=20.0
