Rename the Post settings panel to Document panel

[afercia]

Description

#56481 changed the description of the 'Document settings' section in the Preferences modal from:

'Choose what displays in the panel.'

to:

'Select what settings are shown in the document panel.'

Screenshot:

The problem with this is there's no other occurrence of the 'document panel' terminology in the user interface anywhere. No occurrences in the entire codebase, with the only exception of two occurrences in the changelog.txt file.

As a user, I have no clue what the 'document panel' is and where to find it. To me, this is a clear usability and user experience issue that needs to be addressed:

• Either rename the {post type} tab in the settings panel to 'Document'.
• Or change the description in the Preferences modal dialog.

For clarity: I'm not opposed to the introduction of the 'Document' concept but, if we introduce such a concept, we should use it consistently and name things accordingly.

It is also worth reminding that the labeling of the first tab in the Settings panel is contextual. For post types, it takes the post type singular_name label. if for any reason the singular_name label is not provided it fallbacks to 'Document' and when editing a template it changes to 'Template'. Screenshots:

Also worth reminding that a few years ago this tab was simply labeled 'Document'. See for example the screenshot on this issue from 5 years ago: #8079

Step-by-step reproduction instructions

• Go to the post editor > Options > Preferences modal dialog.
• Observe the description of the 'Document settings' section refers to a 'document panel'.
• Observe there's no usage of the 'document panel' terminology anywhere else in the user interface.
