refactor: remove support for Greenplum

Greenplum is no longer used by any customer and is being removed from the
backend (F1-2435), so the SDK no longer needs to model it.

Drops the hand-written `CatalogDataSourceGreenplum` and `GreenplumAttributes`
classes, their exports from `gooddata_sdk`, and the Greenplum example from the
data-source docs. The Greenplum test went with them: it was already inert,
sitting inside a `"""` block and referencing a `greenplum.yaml` cassette that
does not exist in the repo.

The generated client was updated the supported way rather than by hand. The
`GREENPLUM` enum entry was removed from the two source schemas it originates
from -- gooddata-metadata-client.json and gooddata-scan-client.json -- and
`gooddata-api-client/` was then regenerated with openapi-generator against the
merged schema. The regeneration produced exactly six deletions and no other
drift, which also confirms the checked-in client was in sync with the schemas.

The merged schemas/gooddata-api-client.json was edited line-wise instead of
being rebuilt through the Makefile's `jq -S -s` step. jq 1.6 does not preserve
number literals and rewrote unrelated values (2.6E+9 -> 2600000000, 1.0 -> 1)
across the file; the checked-in copy was produced with jq 1.7+, which does.

This is a breaking change for anyone importing either class by name, including
code that never connects to Greenplum, since the failure is at import time.

JIRA: F1-2435
risk: low
