Why this change?
In cdba864598, we added support for adding
a description which will be displayed under the input of each property
on the client side.
Currently this convention in the locale file is followed:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name: <description for the name property>
links:
name: <description for the name property in link>
url: <description for the url property in link>
```
Since we now want to allow the label to be translated as well, we will
be changing the convention to the following:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name:
label: <label for the name property>
description: <description for the name property>
links:
name:
label: <label for the name property>
description: <description for the name property in link>
url:
label: <label for the url property>
description: <description for the url property in link>
```
If the locale file does not provide a `label` key under the property's
name, the client side will just display the property's name as the
label for the input field.
Why this change?
When editing a objects typed theme setting, the input fields which are
rendered should include a description so that the user knows the purpose
of the field which they are changing.
What does this change do?
This change adds support for adding description to each property in the
schema for an object by following a given convention in the locale file.
For a schema like this:
```
objects_setting:
type: objects
schema:
name: section
properties:
name:
type: string
required: true
links:
type: objects
schema:
name: link
properties:
name:
type: string
required: true
validations:
max_length: 20
url:
type: string
```
Description for each property in the object can be added like so:
```
en:
theme_metadata:
settings:
objects_setting:
description: <description> for the setting
schema:
properties:
name: <description for the name property>
links:
name: <description for the name property in link>
url: <description for the url property in link>
```
If the a description is not present, the input field will simply not
have an description.
Also note that a description for a theme setting can now be added like
so:
```
en:
theme_metadata:
settings:
some_other_setting: <This will be used as the description>
objects_setting:
description: <This will also be used as the description>
```
