Dependabot can't resolve your PHP dependency files

[dependabot-preview]

Dependabot can't resolve your PHP dependency files.

As a result, Dependabot couldn't update your dependencies.

The error Dependabot encountered was:

Your requirements could not be resolved to an installable set of packages.
  Problem 1
    - spell-checker/spell-checker[v0.3.16, ..., v0.3.19] require dogma/dogma ^0.1.15|^0.2.0 -> satisfiable by dogma/dogma[v0.1.15, ..., v0.2.7] from composer repo (https://repo.packagist.org) but dogma/dogma[1.0.0+no-version-set] from root package repo has higher repository priority. The packages with higher priority do not match your constraint and are therefore not installable. See https://getcomposer.org/repoprio for details and assistance.
    - dogma/dogma-dev v0.1.18 requires spell-checker/spell-checker ^0.3.16 -> satisfiable by spell-checker/spell-checker[v0.3.16, v0.3.17, v0.3.18, v0.3.19].
    - Root composer.json requires dogma/dogma-dev 0.1.18 -> satisfiable by dogma/dogma-dev[v0.1.18].

If you think the above is an error on Dependabot's side please don't hesitate to get in touch - we'll do whatever we can to fix it.
