data batch docstring re-formatting: 'Examples:' -> 'Examples'

[sadielbartholomew]

As for #182 over on cfdm, but note that this is only across the data module, i.e:

$ pwd
<path to cf repo>/cf-python/cf/data
$ find . -type f | xargs sed -i 's/Examples:/Examples/g'

in line with our approach to managing development of mostly data modules on lama-to-dask and all other modules on master. I am about to open a corresponding PR on master to cover all non-data modules.

@davidhassell I have opened this PR so the batch update gets done at the first available point, but please prioritise merging of your currently-open PRs before this - it is trivial to manage code updates and to resolve merge conflicts here, much less so (probably) on your PRs.

Great. Can we just merge this now and I'll check for conflicts in the PRs that are currently up?

Sure, whatever you prefer - I just didn't want to create merge difficulties for you, though git may handle it neatly (I suspect it will but I'm not certain)!
