[BUG]: Format strings.xml(values-en) so that string tags are on one line

[adhiamboperes]

Describe the bug

Because some strings are multiline, they are parsed with newlines on translatewiki which cascades down to the translated strings. This causes a problem with display.

Steps To Reproduce

See PRs #5161 and #5009 for details.

Expected Behavior

All strings opening and closing tags should be on a single line:
Correct:
<string name="text_input_default_hint_text">Tap here to enter text.</string>

Incorrect:

  <string name="ratio_default_hint_text" description="The default hint text for the ratio interaction if the placeholder text is not available.">
    Enter a ratio in the form x:y.
  </string>

For plurals, all item opening and closing tags should be on a single line:
Correct:

<plurals name="story_total_chapters">
    <item quantity="one">%s of %s Chapter Completed</item>
    <item quantity="other">%s of %s Chapters Completed</item>
  </plurals>

Incorrect:

<plurals name="chapter_count">
  <item quantity="one">
    1 Chapter
  </item>
  <item quantity="other">
    %s Chapters
  </item>
</plurals>
<plurals name="story_count">
  <item quantity="one">
    1 Story
  </item>
  <item quantity="other">
    %s Stories
  </item>
</plurals>

Additional Context

The linked PRs above highlight the problem strings, but a spot check is needed in strings.xml to make sure all the strings are formatted correctly.
