Space or no space in https://librarycarpentry.org/lc-data-intro/04-exercises/index.html

On this page https://librarycarpentry.org/lc-data-intro/04-exercises/index.html ,
the regex in the answer finds the first example, but not the second one.
This is because in the second example the ‘:’ is immediately following the word, while the regex has a space there.

We think this should be corrected. This page:
https://librarycarpentry.org/lc-data-intro/01-regular-expressions/index.html
does not have this issue.
