Dependency update: ensure we install with at least version 0.9.1 of databricks-labs-blueprint (#2950)

## Changes

In #2920 we introduced a change to ensure that notebook paths are
normalised, resolving #2882. This change depended on an upstream fix
(databrickslabs/blueprint#157) included in the 0.9.1 release of the
dependency. This PR ensures that we run against that release or later.
