Filter button in User interface translation form has more whitespace than it needs

Re-rolled Patch #11, as it's no longer applies to 10.1.x.

Ive tested the patch on 10.1.x and following are my findings

1. The Issues summary is clear and explains the problem
2. Was able to replicate the problem
3. The patch applies cleanly
4. The patch fixes the issue and eliminates the extra space.
5. Did a code review and its a simple change to offload the locale.admin.css css as per #10

Moving the issue to RTBC, skipping before / after screenshots, since a few have been already provided

I am not sure we should actually get rid of this CSS file completely. The file seems to contain several UX enhancements to the translation related UIs. They may seem minor but I assume some thought has been put behind them.

The updated solution as per #23 no longer removes the locale.admin.css file. Instead, it adds `padding-block-start: 0;` for the button. Please review

Verified for both D10 and D11 . The fix looks fine.
