[flake8-blind-except] Change BLE001 to correctly parse exception tuples

[deliro]

Summary

This PR enhances the BLE001 rule to correctly detect blind exception handling in tuple exceptions. Previously, the rule only checked single exception types, but Python allows catching multiple exceptions using tuples like except (Exception, ValueError):.

Test Plan

It fails the following (whereas the main branch does not):

cargo run -p ruff -- check somefile.py --no-cache --select=BLE001

# somefile.py

try:
    1/0
except (ValueError, Exception) as e:
    print(e)

somefile.py:3:21: BLE001 Do not catch blind exception: `Exception`
  |
1 | try:
2 |     1/0
3 | except (ValueError, Exception) as e:
  |                     ^^^^^^^^^ BLE001
4 |     print(e)
  |

Found 1 error.

Neat, thank you! I'm gonna call this a bug instead of an extension of the rule - I don't think it needs to be gated behind preview. Let's just add a couple more tests - the implementation looks good to me though!
