Changing dependencies requirements to be compliant with EBRAINS ESD

[cosimolupo]

In this Pull Request, the requirements of Cobrawap dependencies have been aligned to the latest EBRAINS Software Distribution (ESD) guidelines.

In more detail, referring to the pyproject.toml file:

• the "<0.12" requirement on neo has been removed, since the presence of |'s in config filenames does not seem to be an issue, at variance with initial guess (see also issue Avoid using "|" character in naming profile variants #81 for a discussion on the use of |'s in filenames);
• the ruamel.yaml version requirement has been slightly changed from ">=0.18.3" to "==0.17.32", in order to have an already compiled version also available via spack;
• the pulp dependency has been explicitly added and pinned to "<2.8", so to be compatible with the current constraint "<8.0" for snakemake (see also issues Replace the deprecated 'subworkflow' snakemake feature #57 and Upper limit for PuLP version < 2.8.0 seems to be required #82).

In addition, requirements/environment-docs.yaml file has been updated accordingly.

Finally, there is a potential change to be done also on scikit-image, i.e. relax the version requirement from ">=0.20.0" to ">=0.19.0", so to exploit an already built package in the ESD pipeline. Further checks are needed in this regard.
