Install needs pip upgrade

[cjlegg]

Following the install instructions, https://ukri-excalibur.github.io/excalibur-tests/install/, leads, on multiple machines, to this error:

(excalibur-tests-env) [ucapcjg@locust ucapcjg]$ pip install -e excalibur-tests
ERROR: File "setup.py" or "setup.cfg" not found. Directory cannot be installed in editable mode: /data/ucapcjg/excalibur-tests
(A "pyproject.toml" file was found, but editable mode currently requires a setuptools-based build.)
WARNING: You are using pip version 21.2.3; however, version 24.2 is available.
You should consider upgrading via the '/data/ucapcjg/excalibur-tests-env/bin/python -m pip install --upgrade pip' command.

However after an upgrade of pip the install does proceed.

This instancece of the error was with python 3.9.18, the system python, so above the minimum version stated in the instructions.
