GRPC message FIeldMask parsing

[nirk4m]

Describe the bug
nodejs server using mali.js receives an unary call request with Field Mask porperty.
The field mask attribute on the reqeust payload returns in the following structure update_field_makse: {paths: string[]}
While using ts-proto generated types, the type is generated as native sting array like {update_field_mask: string[]}
check https://github.com/stephenh/ts-proto?tab=readme-ov-file#well-known-types

Expected behavior
unwrap the mask paths into flat string array field
