Inconsistency with GST Transporter ID

[ljain112]

Frappe Support Issue: https://support.frappe.io/app/hd-ticket/13855

Eg Transporter ID: 29AAFCA7488L1Z0 This is a valid transporter ID but Invalid GSTIN and check digit validation is failing.

Proposed Solution

• Avoid check digit validation for all transporter ID and only validate GSTIN regex
• Use directly transporter ID API for all the gstin with transporter or Remove transporter validation at all.
