fix: deploy customDomains

[kushalshit27]

🔧 Changes

Add new badge to the README.md and updates the CustomDomainsHadnler class to improve how custom domain fields are handled during create and update operations. The main focus is on ensuring that certain metadata fields are stripped out when creating or updating custom domains, which helps prevent errors and keeps the payloads clean.

Custom Domains handler improvements:

• Updated the stripCreateFields in CustomDomainsHadnler to also remove created_at and updated_at fields when creating custom domains, preventing unintended metadata from being sent.
• Updated the stripUpdateFields to also remove created_at and updated_at fields when updating custom domains, ensuring consistency and avoiding update errors.
