Incorrect branding image folder documented

We document on this page https://help.sonatype.com/repomanager3/nexus-repository-administration/capabilities/branding-capability#BrandingCapability-ChangingtheNexusRepositoryLogo

By default, the branding plugin will look for the new logo in a file called branding.png in your data directory’s conf folder (e.g. sonatype-work/nexus3/conf/branding.png).

This is wrong.

• there is no fixed image looked for
• one can add img file references to the HTML of the UI: Branding Capability using any image name

Any image file served like this will actually be searched for relative to the $INSTALL-DIR/public/ directory on disk.

For example if I add this HTML in the header:

<img src="$baseUrl/branding.png"/>

Then I should put my image named branding.png at path $INSTALL-DIR/public/branding.png

A browser refresh is required to pick up this image file. 

Expected

Properly document from where to serve branding referenced images.
