fix: replace bare except with Exception in pytest_plugin.py

[harshadkhetpal]

Summary

Replaces a bare except: clause with except Exception: in devel-common/src/tests_common/pytest_plugin.py.

Motivation

Bare except: clauses catch BaseException, which includes KeyboardInterrupt and SystemExit. This can mask critical signals like Ctrl-C. PEP 8 flags this as E722.

Change

# Before
try:
    ...
except:
    ...

# After
try:
    ...
except Exception:
    ...

Testing

No behavior change in normal error paths — only KeyboardInterrupt/SystemExit now propagate as expected.
