[docs-scanner] Broken internal link syntax in billing cycle documentation

[docker-agent]

File: content/manuals/billing/cycle.md

Issue

The file contains an internal link with incorrect syntax that's missing the leading slash:

If you choose to pay using a US bank account, you must verify the account. For
more information, see
Verify a bank account.

This link is missing the leading / and should be /manuals/billing/payment-method.md#verify-a-bank-account. Without the leading slash, the link may not resolve correctly.

The same issue appears in two locations in the file (both tabs of the "Change personal account to an annual cycle" section).

Suggested fix

Update both instances to use the correct link format:

[Verify a bank account](/manuals/billing/payment-method.md#verify-a-bank-account)
