fix(CommandInteraction): cmds with no options throw error

[iShibi]

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

cough So, I totally forgot about slash cmds with no options in #5705. The options param in CommandInteraction#_createOptionsCollection would be undefined for such cmds and thus iterating over it will throw error. This PR fixes the issue by returning an empty collection when options is undefined. I did think of making CommandInteraction#options null at first:

this.options = data.data?.options ? this._createOptionsCollection(data.data.options, data.data.resolved) : null;

but then I saw that before #5705, it was set to an empty array for cmds that have no options, so I went with the empty collection fix.

Status and versioning classification:

• Code changes have been tested against the Discord API, or there are no code changes

The typings for CommandInterationOption#options were also not updated, fixed it in the above commit. No, idea what's up with the changes that linter made tho
