lpad recover_offline doesn't work with pymongo>3.13.0

[JosephMontoya-TRI]

When I use lpad recover_offline in v2.0.3 (with pymongo==4.6.0):

Traceback (most recent call last):
  File "/home/a30107/atomate/bin/lpad", line 33, in <module>

TypeError: 'Collection' object is not callable. If you meant to call the 'count' method on a 'Collection' object it is failing because no such method exists.

I think this is just because Collection.count is deprecated. I think the fix should be straightforward, just update the second condition on line 767 of lpad_run.py to use the more recent method of counting documents. Wanted to raise the issue just in case it falls off my radar and I don't have time to issue a proper fix.
