refactor(lint): genericize lint-runner dispatch and manifest wording

lint-runner's description already promised other linters could be added
without changing its own contract, but Process hardcoded vale-config/
vale-run and .vale.ini by name. Switch to <linter>-config/<linter>-run
naming-convention dispatch so the promise holds. Drop the explicit
Vale callout from the plugin manifests' description/keywords to match.

Addresses a deferred item from PR #85 review.
