This reverts the breaking change to customDomains.list() introduced in a previous PR.

Reverted: Custom Domains API pagination change

The customDomains.list() method has been reverted to its original behaviour, returning a simple array of custom domains instead of a paginated response.

Before (breaking - now reverted):

// Paginated response - NO LONGER THE CASE
const page = await client.customDomains.list({ take: 50, from: "cursor" });
for await (const domain of page) {
    console.log(domain);
}

After (restored original behavior):

// Simple array response - RESTORED
const domains = await client.customDomains.list({
    q: "query",
    fields: "fields",
    include_fields: true,
    sort: "sort"
});
// Returns: CustomDomain[]

Parameters removed:

• take - No longer needed
• from - No longer needed

Return type changed:

• From: core.Page<Management.CustomDomain, ...> (paginated)
• To: Management.CustomDomain[] (simple array)

This ensures backward compatibility with existing code that expects an array response.
