fix: update temporalio min version to 1.11.0 for versioning_behavior support (#8397)

The code uses versioning_behavior parameter in start_workflow() and
execute_workflow() calls, which was only added in temporalio SDK 1.11.0.
The previous min version (1.8.0) caused TypeError in production.

Fixes #8396
