GitHub actions updated, some PHP errors fixed

This PR contains:

- Ci actions (build) refactoring
- Little `Makefile` fix (my mistake in previous PR)
- Updated minimal required versions of composer packages:
  - `psr/http-factory` (`^1.0` → `^1.0.1`)
  - `psr/http-message` (`^1.0` → `^1.0.1`)
  - `laminas/laminas-diactoros` (`^1.3` → `^1.3.6`)
- Tests using minimal and maximal composer package versions
- Disabling `checkMissingIterableValueType` in `phpstan.neon.dist`
- Some typos (wrong class namespaces and annotations) in PHP files :warning: 
- One improvement in `HttpClient::respond` method (variable type hint overriding fixed)
- Added packages testing on CI:
  - `./service/gzip`
  - `./service/reload`
