make pip compile req file path relative to project

[oraNod]

This change results in the paths of the output and input files relative to the project directory when pip-compiling requirements.

Ran this locally and it all worked. I can't comment on the code itself but this also fixed the problem I have in https://github.com/ansible/docsite/pull/245/files#r1610634115

@felixfontein @gotmax23 can you give this one a quick review pls? I tried it locally and it works but I can't say much about the actual diffs :-)

diff --git a/noxfile.py b/noxfile.py
index dac7a7a..bbe56d8 100644
--- a/noxfile.py
+++ b/noxfile.py
@@ -2,7 +2,7 @@ from pathlib import Path
 
 import nox
 
-requirements_directory = Path("requirements").resolve()
+requirements_directory = Path("requirements")
 
 requirements_files = [
     requirements_input_file_path.stem

would have the same effect with less code.

Thanks @felixfontein and @gotmax23 for the reviews!
