Reformat YML files with rake task

These files have been formatted using the new rake task.

Note that I skipped the files that had changes such as single quotes
vs quotes, and whitespace removal to keep this PR as small as it can
possibly be.

I did encounter a flaky test with the fr locale compass test. It got fixed
when I edited the values to keep the quotes around them.

Running the task again will remove whitespaces, comments, ident with two spaces,
and other small things. Ideally, we won't need to run it again for all files, though.
To keep moving forward with the next steps, I didn't fix the task to encounter for these
small scenarios.
