Schema validation for format `uri` allows non ASCII chars

[bernhardreiter]

An uri with a non ASCII character like ® is not detected by the json schema libary we use.

The case is reported upstream with a suggested fix from us: santhosh-tekuri/jsonschema#226

Here is the CSAF 2.0 real world url that triggered the investiation in #474 (see more details there).
