fix(dashboard): padding between rows within tabs

[gbusch]

SUMMARY

There should be padding between rows in a dashboard. Before, this did not work when the rows where within tabs. This is fixed here.
See this issue: #20303

• When you move the charts into tabs, there is no space between plots any more (see first screenshot)

@stephenLYZ I don't really get the meaning of all these pipelines... can you point me to resources to better understand it, so that I can support in getting the PR merged?

[stephenLYZ]

@gbusch It looks like a formatting issue, can you try running npm run format in the frontend?

[gbusch]

@stephenLYZ merged master and run format

[stephenLYZ]

@gbusch Can you resolve the conflict so we are trying to get it?

I think I messed this one up because I did not understand the pipelines at that time...
Probably it is easier to open a new - clean - PR: #21323 and close this one.
