refactor(tool): Change `is_after_fork` method

[gurukamath]

Might be worth it to change the is_after_fork function to just accept the fork short_name instead of the module path. But that should be a different issue. I'll create it.

Hello @gurukamath
I'm a co-facilitator for the Women in Ethereum Protocol (WIEP) Cohort 4. One of our participants is very interested in contributing and would love to work on this issue.

We see that it's currently assigned and wanted to confirm if it's available to be picked up. If so, she would be happy to get started on it.

Thank you!
