Fix dry-schema issue by pinning version 1.10.6

[mt-clearhaus]

This isn't optimal but it's a step in the right direction for fixing:

bundle exec rake test

An error occurred while loading ./spec/lib/pedicel/base_spec.rb.
Failure/Error: require 'dry/validation'

NameError:
  uninitialized constant Dry::Schema::PredicateRegistry

[...]

No examples found.

Finished in 0.00004 seconds (files took 0.18467 seconds to load)
0 examples, 0 failures, 10 errors occurred outside of examples

Error: Process completed with exit code 1.

The main reason for a quickfix is to get the bug fix https://github.com/clearhaus/pedicel/pull/37 released.

Feel free to improve :slightly_smiling_face:

Failure starts from dry-schema 1.11.0.
