Fix-GPR curation for Galactose, Fructose and mannose metabolism

[JHL-452b]

Main improvements in this PR:

As proposed in #849

• Remove ENSG00000171298 from MAR04303;
• Remove ENSG00000198074 from MAR04316;
• Remove ENSG00000141560, ENSG00000172456, ENSG00000167363, ENSG00000162408 from MAR04317;
• Remove ENSG00000141560, ENSG00000162408, ENSG00000116199 from MAR04318;
• Remove ENSG00000141560, ENSG00000172456, ENSG00000167363, ENSG00000162408 from MAR04320;
• Remove ENSG00000100413 from MAR04385;
• Remove ENSG00000164068 from MAR04386;
• Remove ENSG00000116783 from MAR04401;
• Remove ENSG00000241343 from MAR04416;
• Remove ENSG00000198074 from MAR08766;
• Remove ENSG00000116783 and ENSG00000241343 from model as they are not connected to any reactions after this curation.
• Add PMID:2469615;PMID:19158351 to the references of MAR08761 and MAR01472.

I hereby confirm that I have:

• Tested my code on my own computer for running the model
• Selected develop as a target branch
• Any removed reactions and metabolites have been moved to the corresponding deprecated identifier lists

This PR has been automatically tested with GH Actions. Here is the output of the macaw test:

Starting dead-end test...
 - Found 1514 dead-end metabolites.
 - Found 1319 reactions incapable of sustaining steady-state fluxes in either direction due to these dead-ends.
 - Found 1977 reversible reactions that can only carry steady-state fluxes in a single direction due to dead-ends.
Starting duplicate test...
 - Skipping redox duplicates because no redox_pairs and/or proton_ids were provided.
 - Found 447 reactions that were some type of duplicate:
   - 0 were completely identical to at least one other reaction.
   - 13 involve the same metabolites but go in the opposite direction or have the opposite reversibility as at least one other reaction.
   - 447 involve the same metabolites but with different coefficients as at least one other reaction.

A more detailed output from this test run is also committed to data/macawResults/macaw_results.csv.

Note: In the case of multiple test runs, this post will be edited.
