Fix dependency version conflict

[andersy005]

Change Summary

Fixes Upstream CI failures due to version conflicts:

  Requirement already satisfied: decorator>4.1.2 in /usr/share/miniconda3/envs/intake-esm-dev/lib/python3.9/site-packages (from gcsfs==2021.11.1+1.g2dc256b->-r /home/runner/work/intake-esm/intake-esm/ci/condaenv.odj_tsvw.requirements.txt (line 3)) (5.1.1)
  INFO: pip is looking at multiple versions of intake to determine which version is compatible with other requirements. This could take a while.
  INFO: pip is looking at multiple versions of <Python from Requires-Python> to determine which version is compatible with other requirements. This could take a while.
  INFO: pip is looking at multiple versions of fsspec to determine which version is compatible with other requirements. This could take a while.
  
  The conflict is caused by:
      The user requested fsspec 2022.1.0 (from git+intake/filesystem_spec.git)
      The user requested fsspec>=0.8.0
      intake 0.6.5 depends on fsspec>=2021.7.0
      gcsfs 2021.11.1+1.g2dc256b depends on fsspec==2021.11.1
  
  To fix this you could try to:
  1. loosen the range of package versions you've specified
  2. remove package versions to allow pip attempt to solve the dependency conflict
