Bump OpenSTA

[akashlevy]

Catches up from OpenSTA a703bc05 to 7f55dfb1, spanning Silimate/OpenSTA#75, #76, #78, #79 and #82 (plus the #80/#81 revert pair).

Most relevant: Silimate/OpenSTA#82 makes get_property on an empty collection warn and return an empty list instead of aborting with Error 2200.

Greptile Summary

Advances the vendored OpenSTA submodule from a703bc05 to 7f55dfb1, incorporating upstream parser and command-behavior updates.

• Updates only the third_party/opensta submodule pointer.
• Includes the upstream change that makes get_property on an empty collection warn and return an empty list rather than abort.

Confidence Score: 5/5

The PR appears safe to merge, with no concrete changed-code defect identified.

The change only advances the OpenSTA submodule pointer, and the available evidence does not establish a broken build contract, reachable parser regression, or security issue.
