Update table shading tokens color

[danielclickh]

Current colors used for the following tokens have very low contrast with the background:

theme.click.table.row.color.barChart.hover
theme.click.table.row.color.barChart.default

I'd like to update the colors to:

default lightmode = slate 100
hover lightmode = slate 200
default darkmode = neutral 650
hover darkmode = neutral 500

@danielclickh as discussed, we use slate in light mode.

Suggested color and reference images are updated!
