I have removed the override in MediaWiki:Common.css

The PNG file now has the same width as most other project logos, 135px; I can’t say whether the visual change is good or not. (At 150% and 200%, there’s no difference; I don’t know whether the -1.5x and -2x files were inconsistent with the main file before or are inconsistent now.) I’ll still deploy this change, but it might need a follow-up.

All project logos seem to have the same sizing properties applied to them now, and are almost identical in size. What appears to be causing the visual difference between the previous and the new Wikidata logo is the extra horizontal white space that exists around Wikidata's logo in the png file. That difference in the horizontal margins is making Wikidata's logo appear optically smaller in context, in comparison to the equally sized logos (the same is happening with the Commons logo, for example):

The resizing made this more obvious, and now it's easy to perceive how Wikidata's logo is not aligned with the content in the main menu (as Wikipedia's is).
There are a couple of solutions we could apply if we want to make the logo look aligned with the menu's content again: 1. Increase the background-size applied to the Wikidata logo to compensate for the extra white space: I find 146px is a soft spot (although this would introduce an inconsistency in a code that now's nicely aligned), or 2. Create a new logo file with reduced margin.
I think it's also perfectly justifiable if we wanted to leave this as is: the optical misalignment is not inconsistent, it's not causing any UX nor severe layout issues. It's also only affecting the 'old'/Vector legacy look. Thoughts?

I don’t think we should increase the background-size with the current file, since that makes the file look a bit blurry. IMHO, both of the other approaches (new file with less margin, or do nothing) are fine.

Can you add the Nepali logo as well for Wikidata. Thanks
