Add .lint-todo to prettier ignore

The ember-template-lint todo files are not intended to be human-readable, and they can create a lot of churn if prettier gets run against them, particularly if people decide to enable linting against staged files in their project. Since ember-template-lint and prettier both ship by default in the Ember blueprint, we should proactively ignore this directory from being run against prettier.
