Let's update the overall UI display of the sister project snippets in the search results page:
- change the title of the display to be "Results from other Wikimedia projects"
- this might require an update from translatewiki
- change each snippet's footer text link to blue to note that it's a clickable link
- remove the space before each footer link
- there's a space character before the text in each footer link in LTR languages
- make the project footer text more consistent
- update to 'Textbooks from Wikibooks'
- update to 'Texts from Wikisource'
- this might require an update from translatewiki
