avoid double space character in strings

[Presskopp]

There are some strings containing double spaces:

process. Freshly
https://core.trac.wordpress.org/browser/trunk/src/wp-admin/about.php?marks=138#L138

theme. Additionally
https://core.trac.wordpress.org/browser/trunk/src/wp-admin/about.php?marks=134#L134

drafts, locking [...] links. What’s
https://core.trac.wordpress.org/browser/trunk/src/wp-admin/about.php?marks=53#L53

changes before, you’ll pinpoint, coding errors
https://core.trac.wordpress.org/browser/trunk/src/wp-admin/about.php?marks=107#L107

I also found some in PHP files, do you want me to make another ticket for those, like

' . $origin );
https://core.trac.wordpress.org/browser/trunk/src/wp-includes/http.php?marks=491#L491

I made a mistake, see also

please

The about.php ones should hopefully be fixed in https://core.trac.wordpress.org/attachment/ticket/42087/42087.diff — @Presskopp can you double-check when you have a moment?

[Presskopp]

No, I found 7 of them - where do they come from? Made a patch at #42087

[melchoyce]

Thanks. I copied and pasted the copy from a Slack text snippet.

FYI: PHP (spacing) issues will be handled in #41057

Seems to me this ticket can be closed, right? All the double spaces within translatable strings will be handled in #42087 and the ones within code fall under the coding standards to address in #41057. /cc @Presskopp @melchoyce Please do feel free to reopen if I'm missing something.
