chore: ge style updates

[kaloster]

Reason for Change

• Gene Expression color and divider line updates #5838

Changes

• Change chevron color from rgb(153, 153, 153) to colors.gray[300]
• Remove “New” tag from “Group By” (P2 since performance is so bad, maybe users will be more understanding)
• Labels for color scale and dot size legends should be aligned with the labels for download, share, and source data.

Testing steps

• check changes in UI

Checklist 🛎️

• Add product, design, and eng as reviewers for rdev review
• For UI changes, add screenshots/videos, so the reviewers know what you expect them to see
• For UI changes, add e2e tests to prevent regressions
