Cask 'golly' SHA256 mismatch

[moultery]

Verification

• I understand that if I ignore these instructions, my issue may be closed without review.
• I have retried my command with --force.
• I ran brew update-reset && brew update and retried my command.
• I ran brew doctor, fixed as many issues as possible and retried my command.
• I have checked the instructions for reporting bugs.
• I made doubly sure this is not a checksum does not match / SHA256 mismatch error (do not open an issue before trying to open a PR to fix first).

Description of issue

The checksum for the cask golly does not match.

Error: SHA256 mismatch
Expected: 6ffcaa252c9fa131050bfaf5f16aed1138b34a862c20e4aec5cb399c4593bf83
Actual: 9e188f474f6a01cf4c4ddff79d562c8a074ec436cf1cc39503d34a4bd53617c3

I've read the reporting guidelines and run all the verification commands with no effect, and I tried to open a PR as described in the docs, but the brew bump --open-pr command failed:

% brew bump --open-pr golly       
Error: No available formula with the name "golly".
% brew bump --open-pr --cask golly
Error: Cask 'golly' is unavailable: No Cask with this name exists.

Your cask definition for golly has the correct version number, but it was last updated 6 months ago - while the .dmg that it refers to on sourceforge was updated a month ago to fix some bugs, apparently without changing the version number (I guess that's why it didn't come up as needing an update).

Command that failed

brew install --cask golly

Output of command with --verbose --debug
