Missing typing_extensions on macOS

Add a description

Hello,

just discovered my project build and run has been broken after cleanup (make dist-clean)

3: Test command: /Users/xxx/Projects/cpp/pastebin-userver/build-debug/venv-userver-default/bin/python "/Users/xxx/Projects/cpp/pastebin-userver/build-debug/runtests-pastebin_userver" "--service-logs-pretty" "-vv"

Adding typing_extensions manually into venvs fixes problem.

Env:
OS: macOS 26.1
Python 3.14.6 installed via homebrew
userver from develop branch

This looks like a Python 3.14 environment dependency gap. If userver creates the test venv, typing_extensions should probably be part of the generated/default requirements whenever a bundled pytest plugin imports it, rather than relying on it being present from another package. A clean make dist-clean repro is a good regression case because it removes the accidental dependency cache that can hide this.

Yes, but unfortunately I didn't find the right place to add missing module. 😅
