Add gene column in the Mutations table

[arishta]

Fixes cBioPortal/cbioportal#10932

Summary:

• Added gene column to the Mutation table

Detailed summary of the change:

-> The GeneColumnFormatter was already implemented in the codebase, so simply added MutationTableColumnType.GENE to the default columns array in ResultsViewMutationTable.tsx. This makes the gene information visible in the mutation table. Also this column will only visible in the tsv file, not in the UI.

Screenshot:

Here is a screenshot showing Before and After state of the mutation table.

Checks

• Has tests or has a separate issue that describes the types of test that should be created. If no test is included it should explicitly be mentioned in the PR why there is no test.
• The commit log is comprehensible. It follows 7 rules of great commit messages. For most PRs a single commit should suffice, in some cases multiple topical commits can be useful. During review it is ok to see tiny commits (e.g. Fix reviewer comments), but right before the code gets merged to master or rc branch, any such commits should be squashed since they are useless to the other developers. Definitely avoid merge commits, use rebase instead.
• Is this PR adding logic based on one or more clinical attributes? If yes, please make sure validation for this attribute is also present in the data validation / data loading layers (in backend repo) and documented in File-Formats Clinical data section!

Hi @jjgao @inodb Please review this PR, or let me know who to ask for review .
I see a bunch of tests failing, but seems like they are not related to the PR, as I see the same tests failing for other PRs as well.

@arishta-dev Thanks so much for working on this! Could you change the logic to only add the column when downloading the file rather than always showing it? Ideally we wouldn't see it in the UI. The user already knows they're looking at CDKN2A in the browser, but we want to make sure it's clear in the downloaded file too

hi @inodb Thanks for your suggestion - I have modified the code, now gene column will only show in the tsv file.
