@zenstackhq/openapi: zenstack generate silently crashes if openapi plugin config uses empty strings

Description and expected behavior When running zenstack generate, the command should not silently terminate if the plugin openapi configuration in a ZModel file contains empty strings for optional properties.

Screenshots Try using this configuration in a ZModel file:

plugin openapi {
    provider = '@zenstackhq/openapi'
    output = './openapi.yaml'
    title = 'My API'
    version = '1.0.0'
    summary = 'Skyview Weather'
    description = ''
    prefix = '/api'
}

Then run zenstack generate.

> zenstack generate

⌛️ ZenStack CLI v1.0.0-alpha.87, running plugins

The process exits after outputting the above message.

Environment (please complete the following information):

"@zenstackhq/openapi": "^1.0.0-alpha.87",
"@zenstackhq/runtime": "^1.0.0-alpha.87",
"@zenstackhq/server": "^1.0.0-alpha.87",
"zenstack": "^1.0.0-alpha.87"

Additional context Note that, in the above example, zenstack generate works fine if description is omitted entirely.
