docs(readme): give the two screenshots the same width

They were sized with style="height: 320px", which GitHub's sanitizer
strips outright — verified against the /markdown API, which drops style
and keeps width. The width attribute is what the logo above already uses.

48% each so they sit in one row. The two sources are 1.778 and 1.722, so
equal width leaves a ~3% height difference; that reads far better than
mismatched widths, and cropping someone's screenshots to fix it is not
worth it.
