[Bug] SelectPrompt throws a TypeError when given an empty options array

[kevduc]

Environment

• OS: Windows
• Node Version: v16.16.0
• Package: @clack/core (depended on by @sentry/wizard@3.9.2)
• Package Version: v0.3.2

Describe the bug
SelectPrompt throws a TypeError when given an empty options array.
Encountered when using @sentry/wizard@3.9.2, see the related issue: getsentry/sentry-wizard#400

Example:

TypeError: Cannot read properties of undefined (reading 'value')
    at SelectPrompt.changeValue (C:\Users\xyz\AppData\Local\npm-cache\_npx\ddb126e78325956c\node_modules\@clack\core\dist\index.cjs:14:3567)
    at new SelectPrompt (C:\Users\xyz\AppData\Local\npm-cache\_npx\ddb126e78325956c\node_modules\@clack\core\dist\index.cjs:14:3235)

To Reproduce

Pass an empty array for options when creating a new SelectPrompt

Expected behavior
SelectPrompt (and select from @clack/prompts) should require at least 1 element in the array (it doesn't make sense to have no options to select from)
