Fix yaml scanner error

[bleach]

This fixes an error that prevents me from loading the "Manipulating Data with dplyr" lesson in the "Getting and Cleaning Data" course.

I'm not the only one suffering from this; it also closes #504 #502 #498

Previously I saw this error:

Error in yaml.load(readLines(con, warn = readLines.warn), error.label = error.label, :
(/home/gdb/R/x86_64-pc-linux-gnu-library/4.2/swirl/Courses/Getting_and_Cleaning_Data/Manipulating_Data_with_dplyr/lesson.yaml) Scanner error: while scanning a tag at line 205, column 9 did not find expected whitespace or line break at line 205, column 19

It looks as though beginning a string with a '!' became problematic. Fixed by adding single quotes.

Has this been added? I can't access this lesson for the same error so I'm quite stuck..

@kommaqueen no, it has not been fixed, but you can fix it on your machine yourself by finding where swirl is installed and editing the file swirl/Courses/Getting_and_Cleaning_Data/Manipulating_Data_with_dplyr/lesson.yaml and adding single quotes to line 205, and add single quotes so it looks like this:

Hint: '!is.na(c(3, 5, NA, 10)) will negate the previous command, thus telling us what is NOT NA.'

You should only need to add single quotes; the line should look exactly as above minus the quotes.

Your answere was quite helpful!
