Panic data regexes

[cptartur]

Current State

crates/cheatnet/src/runtime_extensions/call_to_blockifier_runtime_extension/panic_data.rs file has regexes for extracting panic data.

Objective

Verify and improve regexes in this file and add unit tests

Additional Context

The existing unit tests only test strings "" but not extracting from shortstrings ''.

The regexes in current version are working but maybe can be written in a better manner.
