Add some missing exports in just-scripts

[christiango]

Overview

On our team, we run our just scripts through typescript using // @ts-check comments.

For the new typescript 5.4 release candidate, we are getting errors like this when importing just like this:

const just = require('just-scripts');

The error messages:

TS9006: Declaration emit for this file requires using private name 'PrettierTaskOptions' from module '"D:/office-bohemia/node_modules/just-scripts/lib/tasks/prettierTask"'. An explicit type annotation may unblock declaration emit.

To resolve these, we're adding the missing exports for types that appear on the public API signature of just-scripts

Test Notes

Only an update to the types exports
