Uninitialized constant URI::REGEXP

[thomaswitt]

After upgrading to ruby 3.3.6 I get the following error when including webmock in the spec_helper for rspec:

An error occurred while loading spec_helper.
Failure/Error: require 'webmock/rspec'

NameError:
  uninitialized constant URI::REGEXP
# ./spec/spec_helper.rb:4:in `<top (required)>'
# ------------------
# --- Caused by: ---
# LoadError:
#   cannot load such file -- webmock/rspec
#   ./spec/spec_helper.rb:4:in `<top (required)>'
No examples found.

Seems to come from the dependency from webmock > em-http-request > cookiejar

I found out that it works if the require 'webmock/rspec' - contrary to the documentation - is moved to spec/rails_helper.rb.
