Rename `Default variables: configuration` to `Default variable details`.

[ypid]

I think Default variable details is the better name for Default variables: configuration because this section explains complex role variables in more detail.

With this change I would also propose to rename the file from defaults-configuration.rst to defaults-detailed.rst. We could use this for new roles and adopt existing roles when reworking them.

Other names:

• Complex variables explanation

What do you think?

Sure, it flows better in English, I suppose (not native speaker). Complex variables explanation is kind of out of the blue IMO, 'default variables' is a known thing in Ansible world.

Default variable details it is then. Thanks. Maybe a native speaker English can take a look?

Copy paste area:

Filename: defaults-detailed.rst
Section heading: Default variable details

One liner to do the change:
mv defaults-configuration.rst defaults-detailed.rst; sed -i 's/defaults-configuration/defaults-detailed/' index.rst

@drybjed Can you reopen? I forgot that GitHub auto closes this issue because of my commit message.
