fix: for Erlang/OTP 27

[kivra-pauoli]

Motivation

We're starting to test some of our tools in OTP 27. This is a step in that direction.

Description

The fixed issue comes from erlang/otp#8069.

Further considerations

The proposal for change (coverage for lib. tests below) comes from WhatsApp/erlfmt#354 (mentioned in that same issue).

Note: we could've not be using a macro for this, but I wanted a small change scope.

Coverage

module          coverage %
crontab         100%
crontab_app     100%
crontab_server  90%
crontab_sup     100%
crontab_time    100%
Total           96%
