The documentation on library properties file format is here
https://arduino.github.io/arduino-cli/0.19/library-specification/

The information for name states

Note that libraries with a name value starting with Arduino will no longer be allowed addition to the Library Manager index as these names are now reserved for official Arduino libraries.

The library properties for our library shows

name=Arduino Cloud Provider Examples

This may not allowed. Go into the library properties file and change the first line to something not beginning with "Arduino" and all should be well. For example

name = Cloud Provider Examples

See if this change corrects the error message.
