Fix some failing round trips

[boutil]

In some Debian environment two of the round trips in to_yaml_spec.rb were failing (those using .month_of_year and day_of_year. Applying the same fix as the one used in 4bf17183be02f8efe17b98c401af40db48a931dc to fix #483 solved the issue.

This patch proposes that corresponding change to /spec/examples/to_yaml_spec.rb.

This fixes one of the tests for me 👍

Before

rspec ./spec/examples/to_yaml_spec.rb:80 # IceCube::Schedule to_yaml should be able to make a round-trip to YAML with .day_of_year
rspec ./spec/examples/to_yaml_spec.rb:114 # IceCube::Schedule to_yaml should be able to make a round-trip to YAML with .month_of_year
rspec ./spec/examples/to_yaml_spec.rb:136 # IceCube::Schedule to_yaml should be able to make a round-trip to YAML whilst preserving exception rules

After

rspec ./spec/examples/occurrence_spec.rb:27 # IceCube::Occurrence to_s accepts a format option to comply with ActiveSupport
rspec ./spec/examples/to_yaml_spec.rb:136 # IceCube::Schedule to_yaml should be able to make a round-trip to YAML whilst preserving exception rules

Remaining failures:

The first test failure is fixed by #528 - but it looks like the second test is still failing 🤔

Looks like following your pattern for the final remaining test worked for my env 👍
