feat(PLU-354): remove connector config models from the SDK (#341)

## Summary
- Replace the typed unions in `CreateSourceConnectorConfig`,
`CreateDestinationConnectorConfig`, `UpdateSourceConnectorConfig`,
`UpdateDestinationConnectorConfig`, and the `*ConnectorInformation`
configs with `Dict[str, Any]`.
- Delete the per-connector config models and their docs (e.g.
`S3SourceConnectorConfig`, `AzureDestinationConnectorConfig`,
`OpenSearchConnectorConfig`, …).
- Bump version to 0.44.0 and add a breaking-change changelog entry.

This decouples the SDK from backend connector schemas — adding/removing
fields on a connector no longer requires an SDK release.

These were deprecated in our docs last year. None of our SDK snippets
use them.

## Test plan
- [ ] CI green
- [ ] Smoke: create a source connector with a plain dict config against
SND and confirm the request goes through

<!-- CURSOR_SUMMARY -->
---

> [!NOTE]
> **Medium Risk**
> This is a breaking change to the SDK surface area: connector `config`
fields switch from typed models/unions to `Dict[str, Any]`, and many
generated connector config classes/docs are removed, which may break
downstream type checks and runtime imports.
> 
> **Overview**
> **Decouples connector configuration from generated SDK models.**
Connector `config` fields for create/update and `*ConnectorInformation`
responses now use `Dict[str, Any]` instead of per-connector typed
unions/models.
> 
> Removes the generated connector config model classes and their
documentation, updates contract tests to assert `config` is a `dict`,
and bumps the SDK version to `0.44.0` with a breaking-change entry in
`CHANGELOG.md` (plus release metadata in `RELEASES.md`).
