• This PR updates an existing tool or tool collection
• This PR does something else (explain below)

This PR updates two things:

1. adds get.rank_genes_groups_df function so the user will get the ranked genes table as a tabular file.
2. adds missing gene_symbols to pl.pca, pl.umap, and pl.diffmap

Thank you @nomadscientist for your suggestion. I hope it helps.

Please make sure that it will not break the GTA tutorials. Otherwise, we will merge this after the GTA.

@pavanvidem I guess it'll conflict with GTA.

[pavanvidem]

Then please mark it as a draft and let it open at least until the end of next week.
