Remove netCDF4<1.7.3 pin #6777
Description
Introduced by #6773 (but will soon need to be updated in the conda feedstock also)
Relevant issue links:
- broke at lockfile update : [CI Bot] environment lockfiles auto-update #6752
It may well be that we actually need a fix in Iris for this, but we're not pursuing that immediately.
The actual issue that occurs is a single test failure, visible in this fragment from the log:
