Echo "some_text" >> .gitignore includes the "" on Windows OS

When creating the .gitignore file on Windows OS the "" are included in the .gitignore which causes git to not ignore the files.

The following lines in Chapter 1 need to be changed to accomodate Windows users:

From:

$ echo "db.sqlite3" >> .gitignore
$ echo "geckodriver.log" >> .gitignore
$ echo "virtualenv" >> .gitignore

To:

$ echo db.sqlite3 >> .gitignore
$ echo geckodriver.log >> .gitignore
$ echo virtualenv >> .gitignore
