fix(APIApplicationCommandAutocompleteInteraction): make options field required

[andre4ik3]

Please describe the changes this PR makes and why it should be merged:

• Makes the options field required for autocomplete interactions
• Even though it is technically "optional" in the docs, in practice it will always be there when receiving an interaction
• The whole point of an autocomplete interaction is that a user is typing out an option. Therefore autocomplete interaction cannot be sent without options.

If applicable, please reference Discord API Docs PRs or commits that influenced this PR:

• Interaction Object Data Structure

Uh oh, I think there is issue with the test

Not sure if there is a better way to do this, I never used type testing before
