Remove Recurring Donation Time Periods

/**

 * This snippet removes some options for recurring donation periods with Charitable's Recurring Donations addon.

 * This might reset or cause odd things to happen to campaigns who resave settings without updating the period if 

 * they already selected some period that is now removed. Just be aware.

 * 

 * This snippet was created Dec 2023 and works with Charitable 1.8.0+.
