When navigating to Abilities -> Create an Ability -> Add executor there should now be default options selected for "platform" and "Exectuor"
I also added a condition for rendering the "delete" button depending on whether or not the user was editing vs creating an ability since you cant delete an ability that hasn't been created yet
It might be annoying to comb through the changes due to the formatting so here are the lines that changed the functionality of the modal: https://github.com/mitre/magma/blob/45c918d8dda508c0bfdf387522a42606fc164e33/src/components/abilities/CreateEditAbility.vue#L38-L42
