[Feature:RainbowGrades] Display RainbowGrades version (#56)

This update allows all users of RainbowGrades (i.e. instructors and
students) to see the build version at the bottom of the RainbowGrades
page. This version info is vital as it allows instructors to know which
version they are currently using.

Having this version information readily available will enable
instructors to provide accurate details when reporting any issues or
errors they encounter. In turn, developers can use this version
information to identify any potential discrepancies caused by outdated
versions and assist instructors more efficiently in resolving their
concerns.
