[#2195] Add cypress test for show tag when grouping by author and by none

Fixes #2195

Proposed commit message

Add cypress test for show tag when grouping by author and by none

Currently, there are no Cypress tests to test the behaviour of the show
tag feature when the report is grouped by author or grouped by none.

Let's add a test for this to ensure the feature is working properly.

Thanks for adding the author-config.csv to test this. I've left a few comments about the tests.

Also, I just realised that the tags feature does not work as expected when using the Group by None option. Each author gets all of the tags of the repo instead of only the ones they tagged. Let's create a new issue for this.

@ckcherry23 the bug with group by none actually happened because of a change I made in this PR to fix group by author. i fixed the bug in this PR already, so all group by options should be working correctly. (also added some tests for this!) do i need to create a new issue + PR to address the original bug?

If everything works as expected now, we do not need a new issue + PR. The current PR seems to have fixed all the issues, is there anything missing?

LGTM @jonasongg! Thanks for making the test cases more robust by comparing chart tags with those on the Zoom tab!

Please update the PR title and description to reflect that both test cases were added ('group by author' and 'group by none').
