Fix 2 issues related to DataSource and remove PostGIS comment

[wmuldergov]

To be able to restore from the BC Gov S3 service we need to set repo2-s3-uri-style to 'path'. This adds that to the PostgresCluster.yaml and values.yaml file. It also corrects the source for 'stanza'

I also removed the comment around setting the CrunchyImage variable when enabling POSTGIS as that is not required and will cause issues.

@caggles are you able to take a look at this PR?

@wmuldergov , I deployed a crunchy chat into one of my namespace without giving the image of postgis and postgis version in the chart. It does not enable postgis. I would be curious how you enabled postgis :).

without explicit instructions in helm chart.

Hello @mishraomp
I set it to:

postgresVersion: 16
postGISVersion: '3.4'

and it worked as expected in Gold DR:

postgres=# SELECT PostGIS_Version();
            postgis_version            
---------------------------------------
 3.4 USE_GEOS=1 USE_PROJ=1 USE_STATS=1
(1 row)

It looks like it pulled:
Image
artifacts.developer.gov.bc.ca/bcgov-docker-local/crunchy-postgres-gis
Image version/tag
ubi8-16.2-3.4-0

Ahh I see, nice, so may be thats the way to go, we just need to mention that, if postgis is needed, mention the postgis version explicitly.
