Fix version specification for redshift-connector (#2467)

## Changes

This PR fixes the version specification for the `redshift-connector`
dependency, introduced in #2305: as written it allows for higher 2.x
versions (e.g. 2.2) as well as downgrades to earlier versions of the
connector (e.g. 2.1.7) that were not used during development or tested.

### Relevant implementation details

When using `~=` with semantic versioning, the complete minimum version
needs to be specified.

### Linked issues

Noticed when reviewing #2466, which downgrades `redshift-connector` to
escape a version constraint on `lxml`. Coincidentally includes #2464.
