Bump OpenSTA

[akashlevy]

Picks up Silimate/OpenSTA#82: get_property on an empty collection now warns and returns an empty list instead of aborting with Error 2200.

Greptile Summary

Updates the bundled OpenSTA revision to include the new empty-collection behavior for get_property.

• Empty collections now produce warning 2200 and return an empty list instead of aborting.
• The upstream change includes regression coverage for empty collections, empty strings, -object_type, warning suppression, and non-empty collections.
• Existing OpenSTA build targets and the APIs consumed by Silisizer remain present.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete build, integration, or caller-level regression identified.

The updated OpenSTA revision preserves the build targets and core APIs consumed by Silisizer, and the changed get_property behavior is explicitly documented and covered by upstream regression tests without a conflicting Silisizer caller.
