Fix/plugin document setting panel name

[ryanwelcher]

Description

This PR is a first pass at close #22049

How has this been tested?

Types of changes

Instead of combining the context.name and potentially missing ownProps.name. I have update the logic to use context.name only if ownProps.name is not defined. This will address the issue of the panel being referenced as plugin-slug/undefined if there is no name property passed to the PluginDocumentSettingPanel component.

It looks good, thank you for proposing this improvement.

There is one file that was removed, I assume by accident. Otherwise, it looks good and should be good to go once my code style changes are applied to conform with WordPress guidelines.

It doesn't look like this change is intentional.

Thanks for catching that! I've readded the file from master
