Remove superflous whitespaces in `layout.html`. by ezio-melotti · Pull Request #107067 · python/cpython

This came up in python/python-docs-zh-tw#496: after adding sphinx-lint to the CI workflow it reported 2 errors caused by trailing whitespace:

sphinx.po:295: trailing whitespace (trailing-whitespace)
sphinx.po:306: trailing whitespace (trailing-whitespace)

These are caused by two strings in sphinx.po (at line 299 and 313), that are taken from layout.html.

This PR remove those spaces from layout.html that should generate a .po without trailing whitespace and fix the issue, even though I wasn't able to test it.

The spaces after the <a>s don't create issues but shouldn't be there, whereas the ones before are the problematic ones and I think they can be removed since in both cases there is a newline, which -- once rendered -- should translate to a space before the link in the output.
