nf-core lint failing for mismatching assets/sendmail_template.txt

Description of the bug

I am trying to merge in the template update after the latest 2.12 release into nf-core/fetchngs and nf-core lint is failing with:

This file is intentionally different and I have already added the block below to .nf-core.yml as you can see here which should exclude this file from being linted but still seeing the failure:

files_unchanged:
    - assets/sendmail_template.txt

Cloning the branch on the PR above and running nf-core lint with the latest version should reproduce the issue locally too.
