Fix invalid regex pattern for ClientRequestId in Chime SDK schema

[Shivam-Shrivastav]

Description

Fixes an invalid regex pattern for ClientRequestId in apis/chime-sdk-voice-2022-08-03.normal.json.

Previous (invalid):

^[-_a-zA-Z0-9]*${2,64}$

Updated (valid):

^[-_a-zA-Z0-9]{2,64}$

The original pattern used an invalid quantifier ${2,64} after a *, which is not valid regex syntax. The corrected pattern enforces 2–64 characters that are alphanumeric, underscores, or hyphens — as likely intended.
