[Documentation] Pattern Name with spaces, but spaces are no longer allowed

[GuzelyaN]

Description:
Documentation includes a Pattern Name and and a Screenshot where the pattern name contains spaces. However this option is no longer correct.

Steps to Reproduce:

1. Open the documentation page: https://docs.zk.email/zk-email-sdk/proof-of-luma
2. Review Example: Proof of Luma and examine Pattern Name in the text and screenshot.
3. Notice that it contains spaces.

Expected Result:
Documentation should reflect the current behavior of the system: Pattern Name must not contain spaces.

Actual Result:
Documentation shows Pattern Name with spaces, which contradicts the actual restriction.
